Exercise: Practicing Range Operations

Elevate your Kotlin expertise by implementing functions with range operations.

We'll cover the following

Problem statement

Implement three functions using range operations as described below:

  • The calculateSumOfSquares function should take an integer n as an argument and return the sum of the squares of all integers from 0 to n.

  • The calculateSumOfEven function should take an integer n as an argument and return the sum of all even numbers from 0 to n.

  • The countDownByStep function should take three integers: start, end, and step, and return a string representation of the numbers from start down to end, with each step being step units apart.

Instructions

In the given code, you have the initial setup featuring the main function and three functions: calculateSumOfSquares, calculateSumOfEven, and countDownByStep. Your task is to implement these functions using range operations as specified.

The actual output when running the provided code should be as follows:
