题目链接:https://leetcode.com/problems/jump-game-ii/?tab=Description   给定一个数组,数组中的数值表示在当前位置能够向前跳动的最大距离.   求解出从下标为0开始到下标到数组最后一个所需要的最少跳动次数!   1.当数组为空或者数组长度等于1时,不需要跳动,因此返回0 否则初始化step=1 2.初始化left=0 right = nums[0] 当left<=right时进入循环体中.  3.从第i=0开始,如果当前跳动距离大于数组…

原题 题意: 是Jump Game的衍生题(题解),题意求跳到最后一格所需最少步数,(默认所测数据永远可以跳到最后一格). 思路: 利用贪心,遍历数组,记录在每一步可跳跃到的最大区域. 1.当前步数 超过已覆盖范围,则表示需要进行跳跃,同时更新已覆盖区域,可覆盖区域. 2.当前步数 在已覆盖范围内,说明无需进行跳跃,同时更新可覆盖区域. /** * @param {number[]} nums * @return {number} */ var jump = function (nums) {…

https://leetcode-cn.com/problems/jump-game-ii/solution/xiang-xi-tong-su-de-si-lu-fen-xi-duo-jie-fa-by-10/ 描述 给定一个非负整数数组,你最初位于数组的第一个位置. 数组中的每个元素代表你在该位置可以跳跃的最大长度. 你的目标是使用最少的跳跃次数到达数组的最后一个位置. 示例: 输入: [2,3,1,1,4]输出: 2解释: 跳到最后一个位置的最小跳跃数是 2.  从下标为 0 跳到下标为 1…

题目 Given a collection of numbers that might contain duplicates, return all possible unique permutations. For example, [1,1,2] have the following unique permutations: [ [1,1,2], [1,2,1], [2,1,1] ] 解答 C语言的实现以前总结过,请见 http://www.cnblogs.com/YuNanlong/p/6…

Given a collection of numbers that might contain duplicates, return all possible unique permutations. For example,[1,1,2] have the following unique permutations:[1,1,2], [1,2,1], and [2,1,1]. 依旧是dfs,不过这次要注意的是排列不允许有重复的vector存在,那么在排列之前应该先排序,然后每次检查的时候,如…
