MAGIC NUMBER in MATLAB and JAVA

Write a program to check a number is magic number or not.

A number is said to be a magic number if the eventual sum of digits of the number is one.

Example 1: 

55

Then 5+5=1--1+0=1

Example 2:

289--2+8+9=19--1+9=10--1+0=1

Example 3:

226---2+2+6=10--1+0=1

Example 4:

19--1+9=10---1+0=1

Example 5:

874---8+7+4=19---1+9=10---1+0=1

MATLAB Code:

User defined function:

 function a=myfunction(n)

x=n;

a=0;

while(x>0)

    b=rem(x,10);

    a=a+b;

    x=(x-b)/10;

end

end

Main body:

x=input('Enter the number');

a=x;

while(a>9)

    a=myfunction(a);

end

if(a==1)

    disp('yes');

else

    disp('No');

end

Output:

JAVA CODE:

import java.util.Scanner;

class Magic

{

public static void main(String args[])

{

Scanner obj=new Scanner(System.in);

System.out.println("Enter the number");

int n=obj.nextInt();

int k=n;

while (k>9)

{

k=mac(k);

}

if(k==1)

{

System.out.println("Yes, the number is magic number");

}

else

{

System.out.println("No, the number is not magic number");

}

}

public static int mac(int x)

{

int b=0;

int rs=0;

while(x>0)

{

b=x%10;

rs=rs+b;

x=x/10;

}

return(rs);

}

}
