Solution: Min Cost Climbing Stairs

Explore how to solve the Min Cost Climbing Stairs problem using dynamic programming. This lesson teaches you to calculate the minimum total cost to reach beyond the last stair by evaluating one or two step moves efficiently. Understand the iterative approach that uses constant space and linear time complexity to optimize solutions for stair-climbing cost problems.

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 ...
