1. Search in Rotated Sorted Array Suppose an array sorted in ascending order is rotated(轮流,循环) at some pivot(枢轴; 中心点) unknown to you beforehand(提前; 事先). (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). You are given a target value to search. If found in th...
You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no duplicate exists in the array. packagecom.leetcode.SearchInRotatedSortedArray;/*** (1)如果target==A[m],那么m就是我们要的结果,直接返回; (2)如果A[m]<A[r],那么说...

leetCode 33. Search in Rotated Sorted Array(c语言版本) bingo酱 I am a fighter 来自专栏 · leetcode每日斩 题目大意: 给定一个旋转升序的数组,所谓旋转就是假设把头和尾连接起来,然后找到最小那个数开始,往后开始就是升序的,直到再回到最小那个数为止。这样看起来就像一个环一样。 然后,现在给定一个数,...
while(start<end){intmid=Math.round(((float)start+end)/2);if(nums[mid]<nums[start]){end=mid-1;}else{start=mid;}}intn=nums.length;bias=(start+n)-(n-1);//此时start是最大值的数组下标,加上模长n,减去最大值的位置n-1,就得到了偏移。因为(位置+偏移)%n=数组下标,即(n-1+偏移)%n...
