81. Search in Rotated Sorted Array II There is an integer arraynumssorted in non-decreasing order (not necessarily withdistinctvalues). Before being passed to your function,numsisrotatedat an unknown pivot indexk(0 <= k < nums.length) such that the resulting array is[nums[k], nums[k+1...
此题是Search in Rotated Sorted Array的加强版,将一个有序数组往右移动若干位。这里的有序数组允许有重复数字。 如果没有重复数字,那么复杂度是O(logn),用二分查找,根据中间值和左右两边的大小,以及和target的大小,来判断缩小一半查找。 但是出现重复数字之后,如果中间值和左右两边的值相等,我们就不知道如何切除...
The array may contain duplicates. 33. Search in Rotated Sorted Array的拓展,数组中允许出现重复数字,这个也会影响我们选择哪半边继续搜索,之前判断左右部分是否有序的方法就失效了,因为可能有这种58555情况,虽然起点小于等于中间,但不代表右边就不是有序的,因为中点也小于等于终点,所有右边也是有序的。所以,如果...
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,0,1,2,2,5,6] might become [2,5,6,0,0,1,2]). You are given a target value to search. If found in the array return true, otherwise return false. Example 1: Input: num...
题目链接:https://leetcode.com/problems/search-in-rotated-sorted-array-ii/ 题目: Follow up for “Search in Rotated Sorted Array”: What if duplicates are allowed? Would this affect the run-time complexity? How and why? Write a function to determine if a given target is in the array. ...
[ 4 5 6 7 1 2 3] ,如果 target = 2,那么数组可以看做 [ -inf -inf - inf -inf 1 2 3]。 和解法一一样,我们每次只关心 mid 的值,所以 mid 要么就是 nums [ mid ],要么就是 inf 或者 -inf。 什么时候是 nums [ mid ] 呢?
Search in Rotated Sorted Array 描述 Suppose a sorted array is rotated at some pivot unknown to you beforehand. 2.1 数组 5 (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return ...
题目 有一个非降序排列的数组 nums,这个数组在某一个位置发生了旋转,给定一个目标数 target。判断这个目标数是否在数组中。 解析 首先看一下旋转数组的性质。当一个数组...
