今天要说的是Rotate Array这题,并不是说这题有多么地难(leetcode把它难度定位为EASY),而是让我理解了JavaScript中以前听说过但是一直没引起重视的一个很重要的性质。 先回到这道题本身,题目很简单,给一个数组,向右移动k位,求新的数组,关键来了,题目要求你Do not return anything, modify nums in-place instead...

For example, with n = 7 and k = 3, the array[1,2,3,4,5,6,7]is rotated to[5,6,7,1,2,3,4]. Note: Try to come up as many solutions as you can, there are at least 3 different ways to solve this problem. [show hint] Related problem:Reverse Words in a String II Credits...

189.Rotate Array Rotate an array of n elements to the right by k steps. For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4]. 解题思路: 使用数组自带的pop()方法和unshift()方法把数组最后一个取出来加入到头部。

第一次二分:找到最小数的位置,参考 find minimum number in rotated sorted array 第二次二分:确定 target 在左侧区间还是右侧,用一个普通的二分法即可找到。 class Solution: """ @param A: an integer rotated sorted array @param target: an integer to be searched @return: an integer """ def sear...
