题目: You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. Input: (2 -> 4 -> 3) + (5 -> 6 -&
题目原文 Selection in two sorted arrays. Given two sorted arrays a[] and b[], of sizes n1 and n2, respectively, design an algorithm to find the kth largest key. The order of growth of the worst case running time of your algorithm should be logn, where n
1.输入班级人数,统计每个人的姓名,性别,年龄:集合与数组 //Console.Write("请输入班级人数:"); //int a = int.Parse(Console.ReadLine()); //ArrayList al = new ArrayList(); //for (int i = 0; i < a;i++ ) //{ // string [] name =new string[3]; // Console.Write("请输入第{0}个人的姓名:&quo
方法一.ArrayList中提供的removeAll方法(效率最低) List1.removeAll(mSubList); 方法二.双重循环(比方法一效率高) 双重循环分为内外两层循环,经过测试,将元素多的list放在外层循环效率更高(mSubList中的元素可能比List1多)(被删除元素的列表List1放在外层循环和内层循环的实现方式有些差别),这里的测试数据是List1中的元素多,实现如下: int maxSize = List1.size(); for (int i = maxSize-
