题意 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. Here are few examples. [1,3,5,6], 5 → 2 [1,3,5,6]…

基础题之一,是混迹于各种难题的基础,有时会在小公司的大题见到,但更多的是见于选择题... 题意:在一个有序数列中,要插入数target,找出插入的位置. 楼主在这里更新了<二分查找综述>第一题的解法,比较类似,当然是今天临时写的. 知道了这题就完成了leetcode 4的第二重二分的写法了吧,楼主懒... class Solution { public: int searchInsert(vector<int>& nums, int target) { , r = nums…

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], 5 Output: 2 Example 2:…

Search Insert Position 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. Here are few examples.[1,3,5,…

题意: 给一个升序的数组,如果target在里面存在了,返回其下标,若不存在,返回其插入后的下标. 思路: 来一个简单的二分查找就行了,注意边界. class Solution { public: int searchInsert(vector<int>& nums,int target) { , R=nums.size(); while(L<R) { )/; if(nums[mid]>=target) R=mid; ; } return R; } }; AC代码…
