Brush questions during summer vacation, ouch ouch

Because the recent work content does not involve programming
I haven't typed the code for a long time
Now because of the school curriculum
Let's review it quickly
The exam was a blast
School tears two lines
Plus, there are physical tests in October
Recently, there are various sports competitions
Ah, ah, ah, ah, ah, ah, ah, come on

The first question is

subject ：

Calculate two 32 An integer A and B And ！

Input Multiple groups of input data , Each group is in a row , Including two no more than binary 32 An integer .

Output Enter... For each group , Output the result in a separate line .

Sample input
1 2
-1 1
Sample output
3
0

Be careful ： Limit input

#include<stdio.h>
int main()
{
    
    long a, b;
    while(scanf("%ld %ld", &a, &b)!=EOF)
    {
    
        printf("%ld\n", a+b);
    }
    return 0;
}

The second question is

subject ：

Calculate two 32 An integer A and B And ！

Input The first line of input data is an integer TT, Express TT Group data . And then TT In line , Each line has two integers A and B.

Output Enter... For each group , Output the result in a separate line .

Sample input
2
1 2
-1 1
Sample output
3
0

Be careful ：

Scanner yes SDK1.5 A new class , You can use this class to create an object .
Scanner input=new Scanner(System.in);

input You can call nextInt()、next()、nextLine() Other methods

nextInt(): it only reads the int value, nextInt() places the cursor in
the same line after reading the input.

next(): read the input only till the space. It can’t read two words
separated by space. Also, next() places the cursor in the same line
after reading the input.( Generally used for Strings )

nextLine(): reads input including space between the words (that is,
it reads till the end of line \n). Once the input is read, nextLine()
positions the cursor in the next line.

import java.util.Scanner;
public class Main {
    
    public static void main(final String[] args) {
    
        Scanner sc = new Scanner(System.in);
        int T = sc.nextInt();
        long a, b;
        for (int i = 0; i < T; i++) {
    
        	// There are only two numbers in each line 
            a = sc.nextInt();
            b = sc.nextInt();
            System.out.println(a + b);
        }
        sc.close();
    }
}

Third question

subject ：

Calculate two 32 An integer A and B And ！

Input Multiple groups of input data , Each group is in a row , It includes two 32 An integer . If both integers are 0, End of input .

Output Enter... For each group , Output the result in a separate line .

Sample input
1 2
-1 1
0 0
Sample output
3
0

Be careful ：
Judge the condition

import java.util.Scanner;

public class input3 {
    
    
    public static void main(final String[] args) {
    
        final Scanner sc = new Scanner(System.in);
        long a, b;
        a = sc.nextInt();
        b = sc.nextInt();
        while (a != 0 || b != 0){
    
            System.out.println(a + b);
            a = sc.nextInt();
            b = sc.nextInt();
        }
        sc.close();
    }
}

Fourth question

subject

A number of 32 Bit integer summation .

Input
Multiple groups of input data , Each group is in a row , It includes a number of 32 An integer . The number at the beginning of the line is the number of subsequent numbers in the line , If the value at the beginning of the line is 0, End of input .

Output
Enter... For each group , Output the result in a separate line .

Sample input
5 1 2 3 4 5
2 -1 1
0
Sample output
15
0

Be careful ：
There are more than two data in each row , Multi row data

#include <stdio.h>
int main()
{
    
	long long int a, b, c = 0;
	char d;
	while (scanf("%lld", &a), a != 0)
	{
    
		while (d = getchar(), d != '\n')
		{
    
			scanf("%lld", &b);
			c += b;
		}
		printf("%lld\n", c);
		c = 0;
	}
	return 0;
}

Fifth question

subject
A number of 32 Bit integer summation .

Input
The first line of input data is an integer TT, Express TT Group test data , Each group is in a row . And then TT In line , The first number in each line is an integer NN, Then there are NN individual 32 An integer .

Output
Enter... For each group , Output the result in a separate line .

Sample input
3
5 1 2 3 4 5
2 -1 1
1 0
Sample output
15
0
0
