【leetcode76】Intersection of Two Arrays II 题目描述: 给定两个数组求他们的公共部分,输出形式是数组,相同的元素累计计数 例如: nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. 原文描述: Given two arrays, write a function to compute their intersection. Example: Given nums1 = [1...
Intersection of Two Arrays(两个数组的交集) 1、题目描述 2、分析 给定两个数组,编写一个函数来计算它们的交集。可以从例子上看出,这道题只需要找到两个数组中相同的数字就好,所以现将第一个数组放入一个set,set里没有重复的元素,并且是排好序的。之后遍历第二个数组看第二个数组中的元素是不是在set中,...
