After searching a lot about how to start studying Dynamic Programming and what are the important topics that I should study and how to practice on them, I found that: 1. Way practice DP 1. Recursion — a procedure that contains a procedure call to itself or a procedure call to a second...

Using dynamic programming, we want to compare by char not by whole words. we need memo to keep tracking the result which have already been calculated memo is 2d array, in this case is 5 * 4 array. It devided problem into two parts ...

72. The difference between them is about the "limit". There is no limit in the leetcode problem. I tried the same code from cs61a to the leetcode problem and get an error saying "Time Limit Exceeded". Then I learned the lesson,during dynamic programming, caching is essential for ...
Use 2d dp array or 1d is fine. dp = [0 for _ in xrange(m+1)] dp size need to be m+1, n+1. Because for the first element need a dp[I-1] to get the do[I]. So we need initial the dp 1 longer and initialize the first row, col. ...
