①英文题目 Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You may assume no duplicates in the array. Example 1: Input: [1,3,5,6], 5Output: 2Example…

题目: 搜索插入位置 给定一个排序数组和一个目标值,如果在数组中找到目标值则返回索引.如果没有,返回到它将会被按顺序插入的位置. 你可以假设在数组中无重复元素. 样例 [1,3,5,6],5 → 2 [1,3,5,6],2 → 1 [1,3,5,6], 7 → 4 [1,3,5,6],0 → 0 解题: 二分法直接搞,找到了返回下标,找不到结束时候的start ==end就是要插入的下标,非递归程序. Java程序: public class Solution { /** * param num…
