今天又是孟哥解惑. 数组里的元素也是指向内存地址么? 这个要分情况的. 无论a[0],a[2]在什么地方,只要其值是基本类型值,就是值的比较,只要其值是引用类型(对象),就是内存地址的比较. Vue官方API:http://cn.vuejs.org/api/#array-_24remove_28reference_29,有个例子array.$remove(reference),参数是对象时,完全没问题,对于基本值,需要再测一下.保险起见,可以用array.splice(index, 1)方法,然

Remove Duplicates from Sorted Array Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory.

给定一个非空且只包含非负数的整数数组 nums, 数组的度的定义是指数组里任一元素出现频数的最大值. 你的任务是找到与 nums 拥有相同大小的度的最短连续子数组,返回其长度. 示例 1: 输入: [1, 2, 2, 3, 1] 输出: 2 解释: 输入数组的度是2,因为元素1和2的出现频数最大,均为2. 连续子数组里面拥有相同度的有如下所示: [1, 2, 2, 3, 1], [1, 2, 2, 3], [2, 2, 3, 1], [1, 2, 2], [2, 2, 3], [2, 2] 最短
