My issue

include <stdio.h>

int main(void) {
int t;
scanf(“%d”,&t);
while(t–)
{
int a,b,x,r,s,y,res,count=0;
scanf(“%d %d %d”,&a,&b,&x);
s=(xx);
r=(ab);
while(s<=r)
{
y=(a-1);
a=a-y;
count++;
r=(ab);
if(s<r)
{
res=(b-1);
b=b-res;
count++;
}
r=(ab);

    }
    printf("%d\n",count);
}

}

I am getting time limit exceeded error???

My code

#include <stdio.h>
int main(void) {
	int t;
	scanf("%d",&t);
	while(t--)
	{
	    int a,b,x,r,s,y,res,count=0;
	    scanf("%d %d %d",&a,&b,&x);
	    s=(x*x);
	    r=(a*b);
	    while(s<=r)
	    {
	        y=(a-1);
	        a=a-y;
	        count++;
	        r=(a*b);
	        if(s<r)
	        {
	            res=(b-1);
	            b=b-res;
	            count++;
	        }
	        r=(a*b);
	        
	    }
	    printf("%d\n",count);
	}

}
