爬楼梯题目分析题解递归动态规划总结题目假设你正在爬楼梯。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?注意:给定n是一个正整数。分析这个题比较简单,算是动态规划的入门题目了,每一级楼梯有两种到达的方式,前一阶和前两阶,很容易就得到:dp(n)=dp(n-1)+dp(n-2),根据这个,就能很容易的得到解法。题解递归根据递推公式,要求n阶就先求n-1和n-2阶

LeetCode
Climbing
Stairs
题意:爬楼梯,一次可以爬1阶或2阶,输入正数n,输出爬到n阶楼梯总共有几种策略。解题思路:方法一:动态规划DP,一次可以上1阶或2阶,那么到第n阶可以从第n-1阶上1阶,或者从n-2阶上2阶,所以到第n阶的策略等于到第n-1阶加到第n-2阶的策略总和。到第1阶1种方法,到第2阶2种方法,到第3阶有1+2=3种方法,到第4阶有2+3=5种方法...其实就是斐波那契数列。时间复杂度:O(n),遍历到n
