this is my solution http://ideone.com/5i1hV2 for the problem
https://www.codechef.com/LTIME16/problems/CHEFB
in this problem i am getting TLE whn n<=100000 and array size<=1000000
but when i removed memset and wrote that step normally by bruteforce ....i got AC........
what happened with that memset();
why?????????????????
this is my modified solution
thanks in advance
