Solution: Min Cost Climbing Stairs

Understand how to solve the minimum cost climbing stairs problem by applying dynamic programming techniques. Learn to optimize the solution for time and space by tracking only necessary states and iteratively calculating minimal costs. This lesson helps you grasp the concept of overlapping subproblems and optimal substructure.

We'll cover the following...

Statement

You are given an integer array, cost, where cost[i] represents the cost of stepping onto the ithi^{th} stair. After paying the cost of the stair you land on, you may climb either one or two steps forward. You may begin your climb from step 00 or step 11 ...
