1.求a+b的和
c++
#include
using namespace std;
int main() {
int a,b;
while(cin >> a >> b)//注意while处理多个case
cout << a+b << endl;
}
java
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
while (in.hasNextInt()) {//注意while处理多个case
int a = in.nextInt();
int b = in.nextInt();
System.out.println(a + b);
}
}
}
python 2.7
#coding=utf-8
import sys
for line in sys.stdin:
a = line.split()
print int(a[0]) + int(a[1])
python 3.5

for line in sys.stdin:
a = line.split()
print(int(a[0]) + int(a[1]))

print(int(a[0]) + int(a[1]))

break;
}
ll = strsplit(l, " ")[[1]]
a=ll[1];
b=ll[2];
cat(as.numeric(a)+as.numeric(b));
cat("\n");
}
Go
package main

b:=0
for {
n, _ := fmt.Scan(&a,&b)
if n == 0 {

a, b = gets.split(" ").map {|x| x.to_i}
puts (a + b)
2.给出N阶方阵所有的数，求方阵中所有数的和
Input：
3
1 2 3
2 1 3
3 2 1
Output：
18
