🧠 Problem Regular Expression Matching Given an input string s and a pattern p, implement regular expression matching with support for '.' and '*' where: The matching should cover the entire input string (not partial). 🏷️ Tags string, Dynamic Prog...
As some folks requested to list down good Dynamic Programming problems to start practice with. So, I am listing down them below and dividing them into different DP problem pattern. Problem listed in group follow a particular pattern and similar appro...
Welcome, future coding master! You've just stumbled upon one of the most powerful tools in a programmer's arsenal: Dynamic Programming (DP). It sounds intimidating, right? Like it's reserved for wizards in high towers. But what if I told you it's jus...
Link : https://www.acmicpc.net/problem/4883 문제 이 문제는 삼각 그래프의 가장 위쪽 가운데 정점에서 가장 아래쪽 가운데 정점으로 가는 최단 경로를 찾는 문제이다. 삼각 그래프는 사이클이 없는 그래프로 N ≥ 2 개의 행과 3열로 이루어져 있다. 삼각 그래프는 보통 그래프와 다르게 간선이 아닌 정점에 비용이 있다. 어떤 경로의 비용은 그 경로에서 지나간 정점의 비용의 합이다. 오른쪽 그림은 N = 4인 삼각 그...
Dynamic Programming (DP) is a fundamental technique in algorithm design, used to solve problems by breaking them into smaller, overlapping subproblems. Two classic examples that illustrate its power are the 0/1 Knapsack Problem and the Longest Increa...
