I work for leetcode and have written the last ~300 problems and articles there. Generally speaking, the trend is for companies to avoid asking dp problems. So if you don't study them, you're usually fine. Most dp problems back then were pretty simple. If you always write a "top down" dp, you're usually fine.Collections of DP Problems in different categoriesDynamic Programming (DP) is a technique to solve problems by breaking them down into overlapping sub-problems which follows the optimal substructure. There are various problems using DP like subset sum, knapsack, coin change etc. DP can also be applied on trees to solve some specific problems.

Two players, who we will call Alice and Bob, take turns removing one of the coins from either end of the remaining line of coins. That is, when it is a player's turn, he or ...To view the solution to one of the problems below, click on its title.

Bellman sought an impressive name to avoid confrontation. Reference: Bellman, R. E. Eye of the Hurricane, An Autobiography.392. Is Subsequence. Given two strings s and t, return true if s is a subsequence of t, or false otherwise. A subsequence of a string is a new string that is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters.
