1 2 3 4	4

SOLUTION

conditional statement

Algorithm analysis

The maximum among four numbers can be found using a conditional statement.

Algorithm implementation

Read the input data.

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

Initialize the maximum value with the first number.

max = a;

Sequentially compare the remaining numbers with the current maximum. If any of the numbers is greater than the maximum, update the maximum value.

if (b > max) max = b;

if (c > max) max = c;

if (d > max) max = d;

Print the answer.

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

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();

int c = con.nextInt();

int d = con.nextInt();

int res = a;

if (b > res) res = b;

if (c > res) res = c;

if (d > res) res = d;

System.out.println(res);

con.close();

}

}

Python implementation

Read the input data.

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

Print the maximum of four numbers.

print(max(a,b,c,d))
