Forward and Reverse Searching of VLOOKING
1. [Forward Search]: - This was the most commonly used function of vlookups, and the formula was: Vlookups (search for values, search for regions, and lock the values in which column, 0/1). There were two points to note here. First, the first column of the search area was the column where the search value was located. Second, 0 meant precise search, and 1 meant rough search. In reality, 0 was often used for precise search. For example, if you want to find the quantity of each product in the seventh month, the formula can be: =VLOOkUP($AA14,$AA6:$AJ10,5,0). - To put it simply, the forward search was to find the data of a later column according to the first column of the search area (the column where the search value was located), such as finding the content of column C according to column B. 2. ** Reverse Search **: - When the search value is at the back of the search area, the normal vlook up will return an error value because the search value is not in the first column. At this time, you can use the reverse search method, the formula is: =VLOOkUP(find value,IF({1,0}, find the column of the value, return the data value),2,0). This formula uses the help of the IF({1,0}, the column where the search value is located, and the return data value). The purpose is to swap the position of the search column and the return column so that the search column is in the first column. For example, when the product is listed in the AK column (after the month), to find the value for July, you can use the formula: =VLOOkUP(AA14,IF({10}, AK7: AK10, AE7: AE10),2,0). - In general, reverse search was to search from right to left by constructing a virtual data column when the search value was not in the first column of the search area. For example, the contents of column A were found according to column B. Read more exciting novels for free
A novel as good as "Forward in Reverse"
Searching for articles and wearing novels in reverse?
Searching for content refers to the process of finding the content of a novel. Sometimes, the content of the novel will be forgotten or lost, so the author or editor needs to find the original content. Reverse-travel novels referred to a plot that traveled back in time to a novel or other work. Such plots often appeared in dystopian or anti-traditional novels to reflect the problems or challenges of the real world.
Air conditioner, cooling machine, forward or reverse
During normal cooling work, the fan of the air conditioner usually rotated clockwise. However, some air-conditioning units had an automatic cleaning function (such as Kelon air-conditioning units). After the cleaning function was turned on, the fan would rotate counterclockwise. Its main function was to blow off the soil on the outdoor unit's heat sink (cooler). There was no fixed mode, which was determined by the external fan used by the air conditioner manufacturer. However, the final effect was the same. They were all suction type, blowing forward. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to control the forward and reverse of the frequency changer
In some situations, it is necessary to control the forward and reverse rotation of the frequency changer. Double switches can be used to realize the forward and reverse rotation start and stop. For example, a maintaining switch was connected to the forward rotation terminal of the frequency changer (some were FWD, here was DI1). When this switch was closed, the frequency changer would rotate forward. After the switch was opened, the frequency changer would stop directly. Similarly, another holding switch is connected to the reversing terminal of the frequency changer (some are REV, here is DI2). When this switch is closed, the frequency changer will reverse. When the switch is opened, the frequency changer stops running. If there is no external regulator, the frequency value of the frequency changer can be set through the panel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reverse bow of cervical vertebra, head forward
The cervical vertebra was reversed and the head tilted forward. It was a disease that caused the physiological curvature of the cervical vertebra to change. The normal cervical spine showed a physiological lordotic curvature, but in this condition, the cervical spine showed a kyphosis that was opposite to the normal physiological curvature, and the head tilted forward. This condition was usually caused by external force on the cervical spine, poor posture (such as looking down at the phone, computer, etc.), or cervical vertebra disease. The patient may have neck stiffness, pain, muscle soreness, numbness of the shoulders and upper limbs, and other symptoms. In severe cases, it will increase the risk of cervical vertebrae disease, such as cervical disc protrusion, cervical vertebrae proliferating, cervical spinal nerve root disease, etc. There were various treatment methods, including medication, physical therapy, rehabilitation therapy, and surgical treatment. The specific plan needed to be evaluated based on the patient's condition, cause of disease, course of disease, and other factors. During the treatment period, the patient should follow the professional doctor's diagnosis and treatment recommendations, maintain good living habits, avoid maintaining bad postures for a long time, and pay attention to cervical health care to enhance the stability of the cervical spine and slow down the development of the disease. In terms of rehabilitation training, for example, McKenzie's rehabilitation therapy needed to follow the principle of gradual progression, that is, no weight, assisted training, weight training, assisted training, and finally, no assistance, weight training. One could not rashly perform difficult movements to avoid worsening the cervical spine problem. There were also some postures such as lion, frog, baby, and reclining that could help to improve related problems. The details were as follows: - Lion Lying: Straighten your legs, place your instep on the ground, and place a pillow on your waist to support it. Use your hands to support your upper body, which can gently strengthen your waist muscles. - [Frog Lying: On the basis of the Lion Lying, the legs are separated. The thighs are vertical to the calves, the toes are facing the sides, and the instep is flat. It can stretch the inner thighs.] - Baby lying: legs together, instep close to the ground, buttocks sitting on the heel, lying on the folded pillow, can relax the back muscles, improve the forward tilt of the hip. - Leaning back: Lying flat on the bed with a pillow under the knee, neck against the bed, head slightly tilted back, and the bed against the neck (to prevent spine sprains), helps to relax the shoulder and neck, improve the neck forward tilt and wealth bag. In addition, there are some actions that can relieve neck soreness, such as looking left and right, neck and hand confrontation, shoulder and neck stretching, etc. However, if self-exercise cannot relieve the symptoms, you should seek the help of a professional doctor in time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to understand the concept of reverse agency and forward agency
A forward agent is a server that is located between the client and the original server. In order to get the content from the origin server, the client sends a request to the agent and indicates the origin server. The agent then forwards the request to the origin server and returns the content to the client. It was a client agent, and its main functions included hiding the real IP address of the client, improving access security, and accelerating access speed (such as by cacheing common resources). It was usually used when the client could not directly access external network resources due to security or policies. A reverse agent is a server agent. When a client requests resources, the reverse agent server receives the request and forwards the request to a server in the internal network (such as a Web server, an application server, etc.) according to the configuration. After the internal server processes the request, it returns the response to the reverse agent server, and the reverse agent server returns the response to the client. Its main functions include Load Balancer (distributing requests to multiple servers to balance the load), cacheing (cacheing common resources to reduce server pressure), security protection (such as filtering malicious requests, authentication, etc.), and so on. It is mostly used in server cluster architecture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
