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
I approched this problem in C language. The idea is to first count number digits (or find order). Let the number of digits be n. For every digit r in input number x, compute rn. If sum of all such values is equal to n, then return true, else false.
You can code the same in any language.
