solve sudoku

The rule of Sudoku is this: In a 9x9 box, you need to fill in the number 1-9 into a space, and make each row and column of the square contain 1-9 of these nine numbers. Also ensure that the space in the thick line divided into 9 3x3 squares also contains 1-9 of these nine numbers. For example, if you have such a problem, you can take a closer look at each line, each column, and each 3x3 square contains 1-9 of these nine numbers.Examples:Answer:The inp

Link (R,a,x,y,i); Dlx. Link (R,b,x,y,i); Dlx. Link (R,c,x,y,i); Dlx. Link (R,d,x,y,i); } } Else { inti=ch-'0'; A=x*9

A good question is also very useful and has made several mistakes. 1. Thinking has an error in enumeration assignment: when the current assignment cannot be completed, it should be to continue the next loop, rather than return false to terminate the enumeration. 2. The generic programing is wrong. Originally, the memset wanted to be written as the generic programing. Then, there will always be only the first group of results No, tears ,,, #include Poj2676

1. Let's see if the phone has been upgraded to the FlyMe OS 3.6.1A (experience version) if you don't find the upgrade method, only upgrade to the FlyMe OS 3.6.1A (experience version) before you can use the nine input method. 2. If determined to be FlyMe OS 3.6.1A (Experience edition), you can set up nine Sudoku Input method. 3. Now we click on "Language and Time"-"system keyboard" as shown in the following figure. 4.
