Climbing Stairs
Detailed guide and Python implementation for the 'Climbing Stairs' problem.
Problem Statement
You are climbing a staircase. It takes n steps to reach the top.
Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top?
Write a function climbStairs(n: int) -> int.
- •1 <= n <= 45
Examples
n = 2
2
There are two ways to climb: 1+1 steps, or 2 steps.
n = 3
3
There are three ways: 1+1+1 steps, 1+2 steps, or 2+1 steps.
