The user is doing ↵
rem = a[i];  ↵

If I set k = 1, and rem = 10^9 Clearly it will timeout, but I was given an unsuccessful hacking attempt. Why?↵
↵
Test case I gave:  ↵
1 1000000000 1  ↵
1000000000  ↵
Result-> Unsuccessful  ↵
↵
I thought compiler would be doing some optimizations. So turned k to 2. Still it gave unsuccessful hacking attempt.↵
IInd Test case I gave:  ↵
1 1000000000 2  ↵
1000000000  ↵
Result-> Unsuccessful  ↵
↵
UPD -> His code got TLE after the final system checks. -_- http://codeforces.net/contest/677/submission/18191327↵
