Function ChooseCOLS
The ChooseCOLS function is used to select a specific column from a set of data based on a specified condition or index and return the column in an array or reference. Its grammar was: =ChooseCOLS(Array, column number 1, column number 2,...). Basic usage example: To extract the first and fifth columns of data from the A1:E10 data area, the formula is =ChooseCOLS(A1:E10,1,5), where A1:E10 is the array data area, and 1 and 5 are the column numbers of the returned array. If there are many column numbers, it can also be expressed in the form of "{1,5}", such as =ChooseCOLS(A1:E10,{1,5}). The default rule for the column numbering of the ChooseCOLS function was to start from left to right. If you wanted to extract columns from right to left, you needed to use negative numbers, such as the first column from right,-1. When searching for a match in reverse, the ChooseColls formula could be used when VLOOkUP was inconvenient. For example, if you want to find the corresponding name in the A1:E4 area of the data source through the code of cell A8 (reverse query), you can first use the ChooseCOLS function: = ChooseCOLS(A1:E4,5,1) to extract the relevant data, and then use the VLOOkUP function: = VLOOkUP(A8,ChooseCOLS(A1:E4,5,1), 2, 0) to search. It also had advanced applications, such as the combination of ChooseCOLS+Match: extracting the data of the corresponding column from the left table according to the order of the fields on the right, the formula was =ChooseCOLS(A2:E10,Match(G1:K1,A1:E1,0)); and the combination of ChooseCOLS+ Filterer: extracting the qualified name and corresponding basic salary from the data of the left table according to the department and seniority information in the right table, the formula was =ChooseCOLS(Filterer (A2:F10,(B2:B10 = H3)*(C2:C10>=I3)),{1,4}). "Choose" was equally exciting. Everyone was welcome to read it!

It means that the Buddha Realm is the realm of superhuman. It can allow one to exert abilities beyond one's control, but it is difficult to learn because of the high consumption.] In addition, the Nine Words Mantra also had a psychological comforting effect on people. If they believed it, they would feel that its effect was real. If they didn't believe it, they would feel that it was useless.
The relationship between the inverse function and the original function
If a function had an inverse function, then the original function and the inverse function were in a one-to-one correspondence, that is, an original function corresponded to an inverse function, and vice versa. From the perspective of domain and range, the domain and range of the inverse function were the domain and range of the original function. Moreover, if a function had an original function, there would be an infinite number of original functions. However, for a particular original function, it would only have one corresponding inverse function (under the condition that the inverse function existed). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is there a listening function?
Online novels usually didn't have the function of listening to books because the function of listening to books usually only appeared in physical bookstores or online bookstores. However, some online novel platforms allowed users to pay for chapters and listen to the content of the chapters that the author had uploaded online. However, this was only the practice of some online novel platforms. Not all online novels had the function of listening to books.
