In codeforces it's something like 4 * 10^8 operations per second.

      You can check it by yourself — put a cycle which does some fixed number of operations in your solution for problem like A+B and look at running time of this solution at given OJ.

      Obviously different operations are running with different speed — doing A+B isn't same as doing A%B.

You can try with this in C...

long long int a;

time_t start_time,end_time;

time(&start_time);

while(1)

{

a++;

time(&end_time);

if((end_time — start_time)==1) //for 1 second

{printf("%lld",a); break;}

}
