题目:Jump GameII 如果要求找最小的调数,考虑扩张的思路. 思路如下: 1.首先找起始位能到达的范围是否覆盖了最终位置,并记录下搜索中的最远能到达的位置值,即max{nums[i] + i}; 2.如果无法到达最终位置,则跳数加一,并从上一次搜索的最后位置开始,向后搜索到上一次记录的最大值所在的位置. 3.重复上面两步,直到找到最终跳数. 注意: 当数组元素只有1个时,跳数是0: 跳数的初值应该是1. int jump(vector<int>& nums){ if (nums…

Given an array of non-negative integers, you are initially positioned at the first index of the array. Each element in the array represents your maximum jump length at that position. Determine if you are able to reach the last index. For example:A = …

引言 一维动态规划根据转移方程,复杂度一般有两种情况. func(i) 只和 func(i-1)有关,时间复杂度是O(n),这种情况下空间复杂度往往可以优化为O(1) func(i) 和 func(1~i-1)有关,时间复杂度是O(n*n),这种情况下空间复杂度一般无法优化,依然为O(n) 本篇讨论第一种情况 例题 1 Jump Game Given an array of non-negative integers, you are initially positioned at the fi…
