Check number is armstrong or not

An Armstrong number is a number that is equal to the sum of its own digits raised to the power of the number of digits. For example, 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 153. Another example is 371, which is also an Armstrong number, because 3^3 + 7^3 + 1^3 = 371. Armstrong numbers are named after Michael F. Armstrong, who first introduced them in 1969.
