I was solving this problem from Round 240 Div 2.
I wrote this code on Ideone Code Link .However when I submitted it on codeforces I got WA on 4th test case which was "1478 194" with answer "312087753" and my output "285334421". When I gave this input to my ideone code,I got the right answer "312087753". But when I tried it with custom invocation of codeforces ,I got the wrong answer again, "285334421". Is their something different between ideone compilers and codeforces compilers.What can I do get to get correct answer on codeforces?
PS- Ideone code was compiled with C++14 and codeforces with C++11 .Is that the issue somehow?
Do not use std::pow when it is not necessary.

Thanks.It was returning 28 for pow(29,1).
pow() has been misusing its power xP
It's bug with MINGW : LINK:
It's not a bug.
double pow (double base, double exponent);So for example,
pow(5.0, 2.0)is evaluated to something like 24.9999...When you use an integer to store such value
int res = pow(5.0, 2.0);The return value is converted to int: (double) 24.9999... = (int) 24.
