【leetcode】70-ClimbingStairs problem ClimbingStairs 题意: 爬台阶问题,每次可以爬1个或者两个台阶,问如果有n个台阶,可以有多少种方法爬到顶部? 解析: 对于n=1,有一种方法;n=2,有两种方法; 对于n>2,对于每一个台阶i到达顶端,最后一步都有两种方式,从i-1再爬一步,或者从i-2再爬2步。 即也就是说到...
假设你正在爬楼梯。需要 n 阶你才能到达楼顶。 每次你可以爬 1 或 2 个台阶。你有多少种不同的方法可以爬到楼顶呢? 解决方案 方法一:暴力法 算法 在暴力法中,我们将会把所有可能爬的阶数进行组合,也就是 1 和 2 。而在每一步中我们都会继续调用 climbStairsclimbStairs 这个函数模拟爬 11 阶和22 阶的情...

Climbing Stairs -- LeetCode 这道题目是求跑楼梯的可行解法数量。每一步能够爬一格或者两个楼梯。能够发现。递推式是f(n)=f(n-1)+f(n-2),也就是等于前一格的可行数量加上前两格的可行数量。 熟悉的朋友可能发现了,这个递归式正是斐波那契数列的定义,不熟悉的朋友能够看看Wiki - 斐波那契数列。依据这个...
