KCHESS - Getting correct output for Test case given in the Problem, but getting WA after submission. Where is my code failing ?

This is my code for the KCHESS Problem. What can be the corner case for which my code is failing? Or is it that I am just printing wrong output to the console? I tried only with the test case given on the problem page and it’s giving the correct output. But after submission I am getting WA.

You’re storing the knight positions in a map and use the x-value of a knight’s position as the key and the y-value as the value in the map. When you have two knights in the same file(x-position) the second knight will overwrite the first one in the std::map and then won’t be there when you check for check-mate.
