LeetCode-81. Search in Rotated Sorted Array II
一、问题描述 这是问题33的升级版,在数组中有重复元素。 二、问题解决 思路和问题33一样,不同点在于判断nums[left]==nums[middle]的时候不能得出左右哪个是单调递增,哪个是循环递增。这时候简单递增一下left,应为此时left一定不为target,可以使代码进一步往下运行。 和 ...

LeetCode-33. Search in Rotated Sorted Array
一、问题描述 一个有序数组,将它截成两部分,然后两部分换位置,得到数组nums。比如对于01234567这个数组,分成012和4567这两个部分,然后把这两个部分调换位置,012放在后,4567放在前,假设得到的数组为nums。 二、问题解决 思路一:最简单的遍历一遍,找到和target相等的数,返 ...
