875. 爱吃香蕉的珂珂 这题时间要求比较严格... 首先,将piles排序,然后二分查找. 总之,答案K肯定位于piles[?]piles[?+1]或者1piles[0]之间 所以我们先二分把?找到,然后再二分找到K即可 class Solution { public int minEatingSpeed(int[] piles, int H) { Arrays.sort(piles); if (H == piles.length) { return piles[piles.length -…

Binary Search基础 应用于已排序的数据查找其中特定值,是折半查找最常的应用场景.相比线性查找(Linear Search),其时间复杂度减少到O(lgn).算法基本框架如下: //704. Binary Search int search(vector<int>& nums, int target) { //nums为已排序数组 ,j=nums.size()-; while(i<=j){ ; if(nums[mid]==target) return mid; ; ;…
