Armstrong Number Calculator

A number is said to be an armstrong if the sum of the cubes of its digits is the number itself. (i.e.)Consider a 2 digit numeral xy, if x3 + y3 = xy, then xy is an armstrong number. For instance, 371 can be written as 33 + 73 + 13, which is equal to 371 and hence it is an armstrong number. Use this calculator, and check if a given number is armstrong or not.

Example

Check if 125 is armstrong number.
125 = 13 + 23 + 53
125 = 1 + 8 + 125
125 = 134

Hence, 125 is not equal to 13+23+53, and so, it is not an armstrong number.
