Now I follow the algorithm,
and work well in my computer.
But I get "Runtime error" when I update.
Is there anything wrong with my code?

Hi, all.
I tried the problem 374,
but I got the "Time limit exceeded".
How can I improve my code?

Also, if I create a array with size 46340,
it become "Runtime error".

#include <stdio.h>

int main()
{
long long int basis=0, p_num=0, m_num=0;
long long int tmp=1;

I had tried many samples,
but I still can not find where the wrong is.
Can someone tell me?
Thanks

this is my code:

#include <stdio.h>

int poly_a, poly_b, poly_c;

int x_is_cross(int y, int x1, int x2)
{
float tmp=0;
tmp = (float) (poly_c-poly_b*y)/poly_a;
if(tmp >= x1 && tmp <= x2)
return 1 ...
