Flowchart of the query function
Function Flowchart was a way to represent an algorithm. It was essentially a graphic representation. It could use components such as nodes, lines, and edges to represent the connections and relationships between the steps in an algorithm. It could help people better understand algorithms and analyze and describe them in a clearer form. A function flow chart usually consisted of three parts: start, process, and end. The start was the node that indicated the starting position of the algorithm, the process was used to indicate the steps of the algorithm, and the end was used to indicate the final result of the algorithm. In addition, you can also use the connection symbols to represent the connections and relationships between the steps in the algorithm. For example, the judgment execution process of the IF function could be represented by a function flow chart. It judged whether a certain condition was met. If it was met, it would return a value, and if it was not met, it would return another value. When judging multiple ranges of values, the process of returning different results according to different conditions could also be clearly shown in the function flow chart. Although the function flow chart was an effective way to analyze an algorithm, when there were too many logical processes in the algorithm, it might become very complicated and not easy to understand. It was widely used in various data structures, algorithm analysis, programming, system design, and other fields. It was a powerful technical means. " Choose " was equally exciting.

How to use the query function
The following are some common query functions: ##1. Vlook-up Function 1. * * Function and parameters ** - This was a vertical search function. The grammar is = VLOOkUP (look up_value, table_array, cor_index_rum,[range_look up]). - The first argument, look up_value, is the value to be looked up. For example, when searching for a person's score, this value could be the cell where the person's name was located. - The second argument, table_array, was the data area to be searched. The query was to be carried out within this data range. - The third argument, cor_index_nam, was the column of the result in the data area. For example, if the result was in the third column of the data area, it would be set to 3. - The fourth argument, range_look up, was the data matching method. If it was set to false or 0, it meant an exact match. If the result could not be found, the function would return #N/A. If it was set to true or 1, it meant an approximate match. If the exact result could not be found, the function would return the maximum value that was less than the search value. It was commonly used in interval judgment and commission calculation. 2. * * Points to note ** - The search value must be in the first column of the data area, or an error value may be returned. - When a duplicate value is encountered, only one result can be returned. This was because VlookUp was a top-down data query. - Unable to find data on the left. If the column you want to find is on the left side of the column where the value is found, you cannot use the Vlook up function directly. 3. * * Case demonstration ** - For example, if the data area was A1: D9, Zhang Fei's name was in cell F3, and his math score was in the third column of the data area, the formula would be = VLOOkUP (F3, A1: D9, 3, 0). ##2. Combination of Index and Match functions (for searching data to the left) 1. * * Index Function ** - For example, to find the corresponding name according to the student number (search to the left), you can use the Index function and Match function. The index function's grammar is as follows: = Index (B: B, Match (G5, C: C, 0)). Where B: B is the column to return the result (here is the name column), the Match function is used to find the position of the specified value in another column, G5 is the value to be found (such as the student number), C: C is the column to be found (such as the column where the student number is located), and the last 0 represents an exact match. ##3. The Look-up Function 1. * * Multi-criteria query example ** - For example, to find the sales volume of product B on the Jingdong platform, the function = LOOkUP (1,0/(B: B = F6)*(C: C = G6), D: D). Here, the construction condition (B: B = F6)*(C: C = G6) is used to determine the rows that satisfy multiple conditions, and then the corresponding values are returned from the D: D columns. 2. * * Find the last number that matches the criteria ** - Find out the sales of Wang Wu on the last day, function = LOOkUP (1,0/(B: B = J4), F: F). The principle was to construct a condition judgment and find the last data that met the conditions. ##4. Choose Function 1. * * Function and grammar structure ** - The function was to select the corresponding content from the list according to the serial number. Syntactic structure = Choose (Sequence number, return value 1,(return value 2)...). - Note: If the value of the "serial number" is a decimal number, it will be rounded off before use. If the "serial number" is less than 1 or greater than the serial number of the last value in the list, the Choose function will return an error value of "#DOWN!". When the value of the "sequence number" is 1, the "value 1" will be returned. When the value of the "sequence number" is 2, the "value 2" will be returned, and so on. ##5. HlookupFunction 1. * * Function and Usage ** - This was a horizontal search function, similar to the Vlook up function, but the search direction was horizontal. When searching, one also needed to specify the search value, the search data area, the number of columns in the data area (here, the number of horizontal columns), and the matching method (exact match or approximate match). "Choose" was equally exciting. Everyone was welcome to read it!
How to use function data query
There are many functions available for data query in Excel. The following are some common functions and their usage: ** 1. Retrieve (Search Function)** <strong></strong></strong><strong></strong> For example, if you want to find the number of bananas, if the data is in the A2:A5 column (assuming it is the fruit name column), the corresponding number is in the B2:B5 column, and the cell where the search value is located is D2, then the function can be set to =LOOkUP(D2,A2:A5,B2:B5). ** 2. Sumif (Condition Summation Function)** Syntactic: =sumif (condition column, sum condition, sum column). For example, if you want to ask for the number of oranges, assume that A2:A5 is the fruit name column, B2:B5 is the number column, and the orange name you want to find is in cell D2. The formula can be set to =SUMIF(A2:A5,D2,B2:B5). ** 3. Dget function (extract unique values from the database)** <strong></strong><strong> When selecting the data, the header must also be selected. For example, if you want to find the data of lemons, if the data area is A1:B5, the search criteria for lemons are in the D1:D2 cell area, and the results to be found (such as quantity) are in the second column, the formula can be set as: =DGET(A1:B5,2,D1:D2). ** 4. dsum function (database function, sum under conditions)** <strong></strong><strong></strong><strong> Similarly, all the data in the parameters needed to include the header. For example, if you want to find all the data of an apple, assume that the data area is A1:B5, the field name of the search result is in the E1 cell, and the search condition is in the D1:D2 cell area. The formula can be set as: =DSUM(A1:B5,E1,D1:D2). ** 5. Sumproduct (Return the sum of the product of the data)** The grammar was: = sumproduct (first data area, second data area, third data area), and so on. For example, if you want to find the number of apples, assume that A2:A5 is the fruit name column, B2:B5 is the number column, and the cell where the search value is located is D2. The formula can be set as: = SUMPPROCEST ((A2:A5 = D2)*B2:B5). In addition, there was also the Xlook-up function. The input was equal to the Xlook-up function. The first argument was the search value (for example, import the name cell), the second argument was the search array (for example, reference the entire name column), and the third argument was the return array. If you want to find multiple data at once, you can set the parameters according to your needs. There was also the MLOOkUP function that could be used for many-to-many search. For example, to find products in a specific store, you need to set the corresponding parameters according to the content to be found, the search area, the column of the results to be found, and the requirements for the results to appear (such as all or the last time, etc.). In addition, you can also use index+match to search (but it may be difficult for beginners to understand), as well as the Vlook up function and other methods to query data. Different functions are suitable for different query scenarios. You can choose the appropriate function according to your specific needs. "Choose" was equally exciting.

Dimethylethyl-Butanol Reaction Flowchart
The experimental flow chart of the Grignard reaction for the preparation of 2 -methvl- 2 -Butanol was as follows: 1. ** Experiment Purpose ** - Learning the preparation and application of Grignard reagents. - Grasp the handling method of low-boiling flammable liquids. - Proficient in purification and recovery of organic liquids, such as the techniques of purification, drying, and separation. 2. ** Basic Principles of Reaction ** - The reaction had to be carried out in the absence of water and oxygen, because the Grignard reagent would decompose when it met water and continue to undergo the substitution reaction when it met oxygen. In this experiment, absolute ether was used as a solution. Because of the high volatile nature of absolute ether, the air in the container could be driven away by ether vapor, thus obtaining the conditions of no water and no oxygen. - The reaction of the Grignard reagent formation was an exothermic reaction, so the dripping speed of the bromic ether should be controlled. It should not be too fast, and the reaction solution should be kept slightly boiling. - The acidic decomposition of the Grignard reagent and the addition product of the keto was also an exothermic reaction, so it had to be carried out under cooling conditions. 3. ** Main reagents and instruments ** - ** Reagents **: 20mL (0.26 mole) of bromic ether, 3.5 g (0.144 mole) of metallic magnesium, 10 mL (0.136 mole) of absolute ether, 45 mL of absolute ether, ether, iodines, concentrated sulfuric acid, absolute potash, and 10% solution of Na2CO3. - ** Instrument **: 250ml three-neck flask, spherical condensing tube, straight condensing tube, constant pressure dropping funnel, separating funnel, drying tube, 50ml round-bottom flask, evaporating head, thermometer (<200°C), thermowell. Another process to synthesize 2 -methvl- 2 -Butanol from a three-carbon and below class of compounds: use-Propanol, replace it with SOCl2 to form 2 -Cl3, and then react with the corresponding Grignard reagent in ether or ThiF. The Grignard reagent then reacts with the corresponding ether, followed by the reaction of the Grignard reagent with the corresponding ether, followed by the reaction of the ether with the corresponding ether. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Flowchart of the Selection Sorting Method
The following is the flow chart of the sorting algorithm: * * 1. Begin ** 1. Suppose there is an array of length n that needs to be sorted. * * 2. First Round Ranking ** 1. Finds the smallest value from the array elements in the unsorted part (index 0 to n-1). 2. After finding the minimum value, it was exchanged with the element at index 0. * * 3. Second Round Ranking ** 1. At this point, the unsorted part becomes the elements of index 1 to n-1. 2. He looked for the minimum value in the unsorted part again. 3. After finding it, exchange it with the element at index 1. * * 4. Sequencing for the next round (Repeat)** 1. For each round, the starting index of the unsorted part increases by 1 (for example, the unsorted part in the third round is index 2 to n-1, etc.). 2. Find the minimum value in the current unsorted part and exchange it with the first element in the unsorted part (that is, the element at the index position corresponding to the current round). 3. This process was repeated until there was only one element left in the unsorted part (that is, the entire array was sorted). For example, for the array [64, 25, 12, 22, 11]: - Round 1: The unsorted part is [64, 25, 12, 22, 11], the minimum value is 11, and the exchange with 64 is [11, 25, 12, 22, 64]. - Round 2: The unsorted part becomes [25, 12, 22, 64]. The minimum value is 12. If you exchange it with 25, you get [11, 12, 25, 22, 64]. - Round 3: The unsorted part is [25, 22, 64], the minimum value is 22, and the exchange with 25 is [11, 12, 22, 25, 64]. - Round 4: The unsorted part is only left with [25, 64]. The minimum value is 25. There is no need to swap. The array sorting is completed.
