what is the complexity for this dp solution !!??
By _QWOiNYUIVMPFSBKLiGSMAP_, history, 6 years ago, In English

the problem is http://codeforces.com/contest/513/problem/C

the solution is http://codeforces.com/contest/513/submission/9761274

i wonder how this solution not TLE it is 1009*1009*6*6*6 which is TLE

Dude. You don't just analyze the complexity by counting for loops

    the each iteration in the for loop work as i clear the dp array so this is the complexity i am confused :s

      For clearing the dp array, I see four for loops and they go till 6,6,6,10009 so how TLE?

        no i mean the dp is in 10009*6*6*6 okay but there is for loop iterating on dp in the main so what is the total complexity ?

          Memoization technique has been used in the solution, which means you just calculate the value for each state only once. Therefore the whole solution proceeds 10009*6*6*6 different states which is pretty far from TLE.
