【Leetcode】Search in Rotated Sorted Array II
题目:和上题一样,只是放宽了条件,旋转数组中数字可以重复出现。思路:由于上题中在判断有序时是根据mid元素值与首尾元素比较得到的,考虑这种情况,10111和11101都是01111的旋转数组,当首尾和中间元素都相等时,无法判断是mid前面的序列有序还是mid后面的序列有序,所以只好用顺序查找。cla...

【Leetcode】Search in Rotated Sorted Array
题目:给定一旋转数组和一整数,判断整数是否在该数组中。旋转数组的定义就是,把数组开始部分的若干个元素移到数组最后。此题假设数组中没有重复元素。思路:之前写的判断情况特别复杂,然后还出错。看了网上题解,这样想就可以了:通过判断mid元素的大小,得知是mid左边的序列有序还是右边的序列有序。每次将tar...
