There is at least one mistake in your code, on line 90

sort(ar,ar+n);

This should be 

sort(ar,ar+k);

because the array has k elements, not n. And accessing elements outside the array is undefined behavior, so the codeforces compiler is probably ok.

The results given by your program differ, depending on the compilation flags. Compiler on CF used different settings than you on your own computer. The problem occurs because you've got technical mistakes in your code. I don't know which one exactly caused that but for example you've got 'dfs' function that is int type but returns nothing.
