Asked in companies
You are given an integer ‘NUM’ . Your task is to find out whether this number is an Armstrong number or not.
A k-digit number ‘NUM’ is an Armstrong number if and only if the k-th power of each digit sums to ‘NUM’.
Example
153 = 1^3 + 5^3 + 3^3.
Therefore 153 is an Armstrong number.
Problem approach
class Solution {
static String armstrongNumber(int n){
int temp = n;
int arm = 0;
while(n!=0) {
int rem = n%10;
arm += Math.pow(rem,3);
n = n/10;
}
if(arm == temp) {
return "Yes";
}
else {
return "No";
}
}
}
