Unique Paths 2 | Dynamic Programming | Leetcode #63

This video explains the unique paths 2 problem which is a followup question of unique paths problem and it is based on dynamic programming on grid.This is an important programming interview question.The prerequisite for solving this problem is the unique paths problem.We need to find the number of ways to reach to the last index starting from 0,0. We can't traverse the cells with obstacles.I have first explained some examples and then shown the intuition along with dry run for solving this problem.CODE LINK is present below as usual.
