Simple Array Sum

Problem

Given an array of N integers, can you find the sum of its elements?

Input Format

The first line contains an integer, N, denoting the size of the array.
The second line contains N space-separated integers representing the array"s elements.

Output Format

Print the sum of the array"s elements as a single integer.

Sample Input

6
1 2 3 4 10 11

Sample Output

Solution

import java.io.*;
import java.util.*;

public class Solution {
    public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
        Scanner sc = new Scanner(System.in);
        int size = sc.nextInt();        
        int sum = 0;

        while(sc.hasNextInt()){          
            sum += sc.nextInt();
        }
        System.out.print(sum);
    }
}

剑指offer--JavaScript版

摘要：剑指在一个二维数组中，每一行都按照从左到右递增的顺序排序，每一列都按照从上到下递增的顺序排序。例如输入前序遍历序列和中序遍历序列，则重建二叉树并返回。其中负数用补码表示。本文为8月牛客网《剑指 offer》刷题做得，现整理出来作为参考。虽然是算法题，但本文用 JavaScript 编写，看了《剑指 offer》以后发现很多问题处理的过程并不是最好的，所以本文仅供参考。以前全部代码 A...
