Link to my submission

It gives no ouput when submitting on 2nd sample test case whereas gives correct output when ran on Leetcode .
My idea is to make the first row and first column same as they are in chess boards , If its possible return the answer else it is Impossible

TC - [[1,1,0],[0,0,1],[0,0,1]]

Correct Output : 2
Your Output : -1

My question is not about Where my code fails :sweat_smile: , it is about why my code is failing to give any output on submission for the same test case that it is passing while I am running it on the same platform :sweat_smile:

I donā€™t know how leetcode works under the hood, but doesnā€™t it give the input as the argument to the function that you have to fill out (e.g. movesToChessboard(vector<vector<int>>& board)) so you donā€™t have to/ mustnā€™t read from stdin?

         cin>>a[i][j];

Yeah, in leetcode we donā€™t have to take input, it is already available in arguments

Thanks :slight_smile: Making a guess as to how Leetcode works - the OP is reading in/ stealing data from cin that was intended for the Leetcode testcase reader/ checker, causing it to go haywire.
