Question

write a program to input a number having three or four digits halve it and find the sum of the individual halves and check whether they are equal or not ​

Answer 1

Answer: I will use the most basic programming language Scratch to do this. Other programming languages are quite similar.

when green flag clicked

ask [number?] and wait

set [count] to (0)

delete (all) of [list]

repeat (length of (answer)) {loop start}

change [count] by (1)

add ((digit (count) of (answer)/2)) to [list] {loop end}

set [sum] to (0)

repeat (length of [list]) {loop start}

change [sum] by (item (1) of [list])

delete item (1) of [list] {loop end}

{script end}

Answer 2

Program: {JAVA}

import java.util.*;

public class Brainly

{

static void main()

{

Scanner sc=new Scanner(System.in);

int n,f,l,s;

System.out.print("Enter an integer: ");

n=sc.nextInt();

if(n>=1000 && n<=9999)

{

f=n/100; //first 2 digits

l=n%100; //last 2 digits

s=f+l;

System.out.println("Sum of the 2 halves:"+s);

}

else

System.out.println("Not a 4-digit number");

}

}
