This is because the default size of OJ's stack is tooooo small.
int array can't be larger than 300000,while long long limit is 200000.(Maybe not very accurate).
So,if you want a bigger one,just add this at the biginning:


#pragma comment(linker, "/STACK:16777216")

which means setting the stack to 16MB,quite enough?

you're right.Thank you for your help.

just don't allocate your arrays in stack.
