Recently i was doing 1607F - Robot on the Board 2 Problem and got RUNTIME_ERROR, Exit code is 2147483647

I used the following lines of code and got ERROR : 134381582

_i += (A[_i][_j] == 'D');
_i -= (A[_i][_j] == 'U');
_j += (A[_i][_j] == 'R');
_j -= (A[_i][_j] == 'L');

while as using these lines of code got AC : 134381437

if (A[_i][_j] == 'D')
    _i++;
else if (A[_i][_j] == 'U')
    _i--;
else if (A[_i][_j] == 'L')
    _j--;
else if (A[_i][_j] == 'R')
    _j++;

on my LOCAL MACHINE it gives me WRONG output. I am confused why is this happening. Let me know if i am missing something
