Hi friends, on an average how many operations can be performed in 1 second,is it 10^7 or 10^9?

In codeforces it's something like 4 * 10^8 operations per second.
And for spoj and codechef?
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
}
