Algorithm Analysis

Compare two numbers and output first the smaller, then the larger one.

The second solution variant – check if $a > b$ , then swap their values using a third variable. Then output the numbers $a$ and $b$ .

Algorithm Implementation

Read the input data.

scanf("%d %d",&a,&b);

Compare and output the numbers in the required order.

if (a < b)
    printf("%d %d\n",a,b);
else
    printf("%d %d\n",b,a);

Algorithm Implementation – swap

Read the input data.

scanf("%d %d",&a,&b);

If $a > b$ , then swap the values of $a$ and $b$ .

if (a > b)
{
    temp = a; a = b; b = temp;
}

Output the values of $a$ and $b$ , where $a \leq b$ .

printf("%d %d\n",a,b);

Algorithm Implementation – ternary operator

Read the input data.

scanf("%d %d",&a,&b);

Calculate the minimum $min$ and maximum $ma x$ values among the two numbers $a$ and $b$ .

min = (a < b) ? a : b;
max = (a > b) ? a : b;

Output the smallest $min$ and largest $ma x$ among the two numbers $a$ and $b$ .

printf("%d %d\n",min,max);

Algorithm Implementation – using functions

#include <stdio.h>

int a, b;

int min(int a, int b)
{
    return (a < b) ? a : b;
}

int max(int a, int b)
{
    return (a > b) ? a : b;
}

int main(void)
{
    scanf("%d %d",&a,&b);
    printf("%d %d\n",min(a,b),max(a,b));
    return 0;
}

Java Implementation

import java.util.*;

public class Main
{
    public static void main(String[] args)
    {
        Scanner con = new Scanner(System.in);
        int a = con.nextInt();
        int b = con.nextInt();
        
        System.out.println(Math.min(a,b) + " " + Math.max(a,b));
        con.close();
    }
}

Python Implementation

a, b = map(int, input().split())

if a > b:
    a, b = b, a

print(a, b)

C# Implementation

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleAppCSharp
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] values = Console.ReadLine().Split(' ');
            int x = int.Parse(values[0]);
            int y = int.Parse(values[1]);

            int min = (x < y) ? x : y;
            int max = (x > y) ? x : y;
            Console.WriteLine("{0} {1}", min, max);
        }
    }
