time complexity and time limit
By himank, 13 years ago, In English

My code (C++) is having worst case complexity of 10^8 (precisely 9*10^7 )and time limit for the question is 3 sec. I am getting TLE, so what should be worst case complexity to pass the test cases.

    In that case, try heavy optimization. Of course, if it's not a DP and you mean just that the complexity is like O(N2K) where N ≤ 103 and K ≤ 90, then there can be a big bad constant factor.

    Try running your code on your system and check how long it runs on some worst cases.

      I checked it on my system it was taking around 4 sec for worst case. But finally i corrected it and got it accepted. :) Thanks BTW.
