What is Weak Arm number
Weak arm numbers are those where the number is equal to the sum of the digits to the power 'n'. 'n' is the number of digits in the number and it is maximum for the unit digit value and decreases by one
For example to check whether 153 is an Weak Arm number, the sum would be like 1 1+ 5 2 + 3 3. 153 is not weak arm number. Examples of weak arm numbers are 89, 135, 175, 518, 598
import java.io.*;
public class WA
{
void showWeakArm() throws Exception
{
int c=0;
int a,d,b,n;
double sum=0;
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("enter the no.");
n=Integer.parseInt(br.readLine());
b=n;
while(b >0)
{
c++;
b=b/10;
}
b=n;
while(b >0)
{
a=b%10;
sum=sum+Math.pow(a,c);
b/=10;
c--;
}
if(n==(int)sum)
System.out.println(n+ " is A WeakArm Number");
else
System.out.println(n+ " is Not A WeakArm Number");
}
public static void main(String args[]) throws Exception
{
WA ob=new WA();
ob.showWeakArm();
}
}
