If runtime error, check for division by 0
In USACO, make sure spaces are right
Substring 2nd parameter is the LENGTH of the String
Remember that in for (int i = 0; i < k; i++) to not update k in body
When doing ceil or floor or square root, remember that the parameters themselves need to be doubles
Read the problem specifications very carefully
Check for bounds in DP
