note dp[0][0][0] = 0 (don't have to initialize anything) And implemented this algorithm in Python: 274520784 However, this code WAs for test case 8, with my answer of 11 being higher than the expected answer of 9. I have read the editorial for this question, and I believe the DP...

Implementation-wise, a 2D DP is relatively easy. With some math, the problem itself can be converted to a subset sum problem (LC416). Thank you very much! It took a whole hour to understand the first example) I had to write an example in python to get intermediate results and understan...
