我是用hashset<T>来实现的 具体如代码所示 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace JiaoJi { class Program { static void Main(string[] args) { ]{,,,,,,,}; ]{,,,,}; HashSet<int> hashset=new HashSet<int&g
Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: A: a1 → a2 ↘ c1 → c2 → c3 ↗ B: b1 → b2 → b3 begin to intersect at node c1. Notes: If the two linked lists have
题目描述: Given two arrays, write a function to compute their intersection. Example:Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2, 2]. Note: Each element in the result should appear as many times as it shows in both arrays. The result can be in a
直接上代码,有三种方法,第三种调用库函数效率最高 # ! /usr/bin/env python # encoding:utf-8 if __name__ == '__main__': a = [1,2,3,4,5] b = [2,3,6,7] u =[] dif =[] intersec = [] '''方法一,最简单的方法,容易想到的''' for item in a: u.append(item) if item in b: intersec.append(item) if item no
-- 克隆 function Clone(object) local lookup_table = { } local function _copy(object) if type(object) ~= "table" then return object elseif lookup_table[object] then return lookup_table[object] end local new_table = { } lookup_table[object] = new_ta
循环判断2个数组 将相同的公共元素复制到新数组中即可 import java.util.Arrays; public class count_same_number { public static int[] join(int[] a,int[] b) { int count=0; int new_target[]=new int[Math.max(a.length, b.length)];//新数组 int index=0; for(int i=0;i<a.length;i++) { for(
public static void main(String[] args) {Set set = new HashSet();Set set1 = new HashSet();set.add("sanny");set.add("mary");set.add("bill");set.add("tom");set.add("tony");set.add("mark");set.add(&q
http://www.jb51.net/article/40385.htm 代码如下: /** * each是一个集合迭代函数,它接受一个函数作为参数和一组可选的参数 * 这个迭代函数依次将集合的每一个元素和可选参数用函数进行计算,并将计算得的结果集返回 {%example <script> var a = [1,2,3,4].each(function(x){return x > 2 ? x : null}); var b = [1,2,3,4].each(function(x){re
原创: Z Excel高效办公之VBA 2017-03-10 Part 1:逻辑过程 已有两个数组,要求单个数组中信息无重复 以最短的数组作为循环,分别判断该数组中的元素是否在另一个数组中 如果某一元素在另外一个数组中,则将其保存到结果数组中 Part 2:代码 Function funIntersection(array1, array2) Rem>>求两个集合的交集 Rem>>要求原数组无重复信息 Dim len1 Dim len2 Dim cycle Dim cycleArr
求两个列表的差集 >>> a = [1,2,3] >>> b=[1,2] >>> #################################### >>> #两个列表的差集 >>> ret = [] >>> for i in a: if i not in b: ret.append(i) >>> ret [3] >>> #两个列表的差集2 >>
