"""Write a function to check if a number is Disarium or not.
A number is considered Disarium when the sum of its digits, each raised to the power of
their respective positions, equals the number itself.
For example, consider the number 175. Here,
1^1 + 7^2 + 5^3 = 175
So, 175 is a Disarium.

Example
input:135
output:True

input:518
output:True

because 1^1 + 3^2 + 5^3 = 135"""
