umm try checking the constraints again its x<n and ur x and n are equal, it fails coz of that probs
its n=10^9,x=10^8
my bad my bad
I think it must be optimized by c++ itself
Run the code in custom invocation to see its running time in CF environment.
Try adding -O2 to your compilation flags locally, then it should be really fast.
Looks like it is fast enough, there are at most 10^10 operations, which should run in time.
10^10 operations should almost never run in time.
