Min Cost Climbing Stairs
Detailed guide and Python implementation for the 'Min Cost Climbing Stairs' problem.
Problem Statement
You are given an integer array cost where cost[i] is the cost of ith step on a staircase. Once you pay the cost, you can either climb one or two steps.
You can either start from the step with index 0, or the step with index 1.
Return the minimum cost to reach the top of the floor.
Write a function minCostClimbingStairs(cost: List[int]) -> int.
- •2 <= len(cost) <= 1000
- •0 <= cost[i] <= 999
Examples
cost = [10,15,20]
15
Start at index 1, pay 15, and climb to the top. Total is 15.
cost = [1,100,1,1,1,100,1,1,100,1]
6
Start at index 0, pay 1, climb to 2, pay 1, climb to 4, pay 1, climb to 6, pay 1, climb to 7, pay 1, climb to 9, pay 1, climb to top. Total is 6.
