Triangle (LeetCode 120) | Easy tutorial | Bottom-up Top-down dynamic programming | StudyAlgorithms смотреть онлайн

This problem is helpful to understand how dynamic programming actually works. Given a triangle of integers, we need to find the minimum sum possible starting from the top most element. The problem follows an optimal sub-structure property and can be solved using either the top-down approach or the bottom-up approach using memoization.
