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
31
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);
}
}
A Very Big Sum

Scanner sc = new Scanner(System.in);
int size = sc.nextInt();
long sum = 0;
while(sc.hasNextInt()){
sum += (long)sc.nextInt();
}

摘要：劍指在一個二維數(shù)組中，每一行都按照從左到右遞增的順序排序，每一列都按照從上到下遞增的順序排序。例如輸入前序遍歷序列和中序遍歷序列，則重建二叉樹并返回。其中負(fù)數(shù)用補(bǔ)碼表示。 本文為8月?？途W(wǎng)《劍指 offer》刷題做得，現(xiàn)整理出來作為參考。雖然是算法題，但本文用 JavaScript 編寫，看了《劍指 offer》以后發(fā)現(xiàn)很多問題處理的過程并不是最好的，所以本文僅供參考。以前全部代碼 A...
