Brief introduction If you often brush leetcode, you will find many problems with dynamic programming tags. In fact, there are 115 topics with DP tags, most of which are medium and difficult, accounting for 12.8% of all topics (September 2018), which is the second largest problem. If we can systematically study the topic of DP, I believe it will greatly improve the speed of solving problems, and also help t
