Given an array of integers, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Please note that…
题目: 给定一个数组candidates和一个目标值target,求出数组中相加结果为target的数字组合: 举例: For example, given candidate set [2, 3, 6, 7] and target 7, A solution set is: [[7],[2, 2, 3]] 从举例中可以看出,同一个数字可以使用多次,且结果是唯一的: 解题思路: 我个人感觉该题目一点也不难,其实也是一个递归的过程,当达到递归条件时,就将结果加入结果集: 首先题目没说给的数组有啥特…
完成几个小代码练习?让自己更加强大?学习新知识回顾一下基础? 1.输入数组计算最大值 2.输出数组反向打印 3.求数组平均值与总和 4.键盘输两int,并求总和 5.键盘输三个int,并求最值 /* 要求:输入一组数组,计算出最大值. */ public class cesi{ public static void main (String[] args) { int[] array = {5, 15, 100, 999, 1000}; int max = array[0]; for (int…
