Test instructions: Oh, my God! I can not understand test instructions, but also to go through other people's code to understand! Given a string, the total value of the string 26 binary is obtained.Idea: ' A ' ~ ' Z ' is 1 to a, "AA" =26+1=27, "BA" =26*2+1=53, "CBA" =26*26*3+26*2+1. Equivalent to 321 (decimal), then is 10*10*3+10*2+1, said 3rd, C in 3rd place, in the 1th bit is 1~26 value, that is, 3, in the 2nd position is 3*26, and then 3rd is 3*26*26; b is 2*26, A is 1. In the final analysis,
Given a column title as appear in an Excel sheet, and return its corresponding column number.For example: 1, B, 2 C-3 ... 27 AA, Z There is nothing to say about this problem. Just be honest and count on it.Use the POW () method inside math (). Then loop through one of the counts and add it up. (This should be a capital letter only, see example).The code is as follows. ~ (In fact, the code

NPOI_2.1.3 _ Learning Record (3)-add content and hyperlink (URL, Email, and Sheet) to a specified cell in Excel, and npoi_2.1.3sheet
In the previous article, we created four sheets. Now we insert content to the specified cells and the Specified Cells in the specified Sheet and add links. In the code for creating a Sheet
In Excel, you create the hyperlink code in bulk (connect to sheet in the current document), and in column B in Sheet1, you create a series of hyperlinks that are the other sheet in this document, such as creating a macro under Sheet1 code as follows.SUB Macro 1 ()Dim Temp, Temp2Dim I, Jj = 1For i = 5 to 74temp = "' G" J "'!

This problem can be seen as a 26-in-one question. 26 binary means you can combine up to 26 different symbols to represent a numeric value.Therefore, the value of the ABC Representative is: a*262+b*261+c*260=1*262+2*261+3*260, other letter combinations and so on.The following method is a very intuitive idea, but to invoke the C + + library function pow (x,a), the calculation time will be longer.The POW (x,a) can calculate the a power of X, and the ASCII code of ' a ' is 64.classSolution { Public:
For a detailed explanation, see the analysis of another problem relative to it, the process here is her inverse process. Another question.The code is as follows:Class Solution {public:intTitletonumber (Strings) {String::reverse_iterator iter1, iter2; Iter1 =s. Rbegin (); Iter2 =s. rend ();intOutput =0; for(; Iter1! =s. rend (); iter1++) {if(*iter1==' Z ') {if(Output = =0) {*iter1=' 0 '; Output =1; }Else{*iter1=' A '; Output =1; }Continue; }if(*iter1==' Y ') {if(Output = =1) {*iter1=' 0 '; Output
The 1,10 is converted into 26, but it needs to be noticed minus 1 first.2,CHR (i): Returns the ASCII character corresponding to the integer i. Contrary to the Ord () effect.3, reverse return can be directly used res[::-1].There is no append (Var), insert (Index,var), Pop (Var), and other methods that are owned by a list of string types in 4,python, which require special attention.5,python does not have to declare data types like C + +, but can also be declared, such as string= ' (string), list=[

I'm glad that I just implemented a function. In Excel VBA programming, I can finally list all the sheet and click one of them to automatically jump over! The Code is as follows:
