题目地址:https://leetcode-cn.com/problems/search-in-a-sorted-array-of-unknown-size/ 题目描述 Given an integer array sorted in ascending order, write a function to search target in nums. If target exists, then return its index, otherwise return -1. However, the array size is unknown to ...
LeetCode系列(六)- Search in Rotated Sorted Array 假设按照升序排序的数组在预先未知的某个点上进行了旋转。 ( 例如,数组[0,1,2,4,5,6,7]可能变为[4,5,6,7,0,1,2])。 搜索一个给定的目标值,如果数组中存在这个目标值,则返回它的索引,否则返回-1。 你可以假设数组中不存在重复的元素。 你的算法...
题目链接:https://leetcode.com/problems/search-in-rotated-sorted-array/题目: Suppose a sorted array is rotated at some pivot unknown to you beforehand. 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 the array return its index, o...
此时medium = 3,正中间的数是0,根据情况2的提示,我们先判断到nums[low] = 4 是比nums[medium] = 0大的,说明旋转升序的起始点,这里是位置3,包含这low到medium之间,所以才会出现这种情况,同时这种情况也说明了,从medium到high之间的数,肯定是升序的,即Subnums2 = nums[medium to high]是升序数组,如果nums[...
LeetCode-33-搜索旋转排序数组(Search in Rotated Sorted Array) 33. 搜索旋转排序数组 整数数组nums按升序排列,数组中的值互不相同。 在传递给函数之前,nums在预先未知的某个下标k(0 <= k < nums.length)上进行了旋转,使数组变为[nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ....
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. 【二分思路】 分情况讨论,数组可能有以下三种情况: 然后,再看每一种情况中,target在左边还是在右边,其中第一种情况还可以直接判断target有可能不...
输出: 4 示例2 输入: nums = [4,5,6,7,0,1,2], target = 3 输出: -1 解题思路: 主要是利用二分查找法来解题 因为原始数组是升序数组,所以旋转之后的数组必是两个升序数组的合并 首先先通过一次二分查找的方式,找到第二个升序数组的第一项l,即有序数组的最小一项 ...
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 …
Can you solve this real interview question? Search in Rotated Sorted Array - There is an integer array nums sorted in ascending order (with distinct values). Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1
There is an integer array nums sorted in ascending order (with distinct values).Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1 <= k < nums.length) such that the resulting array is [nums[k], nums[k+1]
