56 741 Thanks. for problem F posterize, I understand you divide like this DP(i,j) = min_k {DP(k, j-1) + cost(k+1, i)} where i = # red values, using j = #allowed values. Can you please guide me what was your strategy for this specific test? Hey I was wondering if I could have your solutions to certain Kattis problems?

Also see my profile page. I have seen some people doing it only on 3 for loops, but I don’t understand why it works. ... ? Unfortunately there aren’t many active coders on Kattis, which is a pity since it holds a lot of high quality algorithmic problems. My python program for 0-1 sequences of kattis works properly, but I am still getting Time Limit Exceeded… Is python code slow or Should use special formula to solve this problem??
