Run-Time Check Failure #2 - Stack around the variable 'arr' was corrupted.

This error typically occurs when there is a buffer overflow or when memory is accessed beyond its allocated size. It suggests that the stack memory for the variable 'arr' has been overwritten or corrupted, potentially causing unexpected behavior or crashes.

To fix this issue, you should review your code and ensure that you are not accessing memory beyond the allocated size of your array 'arr'. Make sure that any loops or operations involving 'arr' are properly bounded and do not exceed its size. Additionally, double-check for any potential buffer overflows or memory access issues in your code.
