Hella Loops Part 01

Problem 01

Problem Statement

You are tasked with creating a function named getEvenNumbers that returns an array of even numbers between the given start and stop values, inclusive.

Your getEvenNumbers function should accept two parameters:

1. start: an integer representing the starting number.
2. stop: an integer representing the ending number.

The function should return an array of integers representing all the even numbers in the specified range.

Here are some examples:

• getEvenNumbers(2, 6) should return [2, 4, 6] because all the even numbers between 2 and 6 (inclusive) are 2, 4, and 6.

Constraints:

• The input start and stop are integers.

Solution

Problem 03

Problem Statement

You are tasked with creating a function named getSquareNumbers that returns an array of numbers between the given start and stop values where each number is a perfect square (e.g., 1, 4, 9, 16, ...).

Your getSquareNumbers function should accept two parameters:

1. start: an integer representing the starting number.
2. stop: an integer representing the ending number.

The function should return an array of integers representing all the perfect square numbers in the specified range.

Here are some examples:

• getSquareNumbers(1, 20) should return [1, 4, 9, 16] because all the perfect squares between 1 and 20 (inclusive) are 1, 4, 9, and 16.

{Try It!}(node .guides/getSquareNumbers/try-it-01.js)

• getSquareNumbers(10, 50) should return [16, 25, 36, 49] because all the perfect squares between 10 and 50 (inclusive) are 16, 25, 36, and 49.

{Try It!}(node .guides/getSquareNumbers/try-it-02.js)

Constraints:

• The input start and stop are integers.

Solution

node .guides/secure/getSquareNumbersTest.js

Problem 04

Problem Statement

You are tasked with creating a function named getRange that returns an array of numbers starting from 0 up to (but not including) the stop value.

Your getRange function should accept a single parameter:

1. stop: an integer representing the ending number.

The function should return an array of integers representing the sequence of numbers from 0 to stop - 1.

Here are some examples:

• getRange(5) should return [0, 1, 2, 3, 4] because the numbers from 0 up to (but not including) 5 are 0, 1, 2, 3, and 4.

{Try It!}(node .guides/getRange/try-it-01.js)

• getRange(3) should return [0, 1, 2] because the numbers from 0 up to (but not including) 3 are 0, 1, and 2.

{Try It!}(node .guides/getRange/try-it-02.js)

Constraints:

• The input stop is a non-negative integer.

Solution

node .guides/secure/getRangeTest.js

Problem 06

Problem Statement

You are tasked with creating a function named getRangeWithStartAndStep that returns an array of numbers starting from the start value, incrementing by the step value, and ending before the stop value.

Your getRangeWithStartAndStep function should accept three parameters:

1. start: an integer representing the starting number.
2. stop: an integer representing the ending number.
3. step: an integer representing the interval between numbers.

The function should return an array of integers representing the sequence of numbers based on the given parameters.

Here are some examples:

• getRangeWithStartAndStep(2, 10, 2) should return [2, 4, 6, 8] because starting from 2, incrementing by 2, and ending before 10 results in 2, 4, 6, and 8.

{Try It!}(node .guides/getRangeWithStartAndStep/try-it-01.js)

• getRangeWithStartAndStep(3, 20, 5) should return [3, 8, 13, 18] because starting from 3, incrementing by 5, and ending before 20 results in 3, 8, 13, and 18.

{Try It!}(node .guides/getRangeWithStartAndStep/try-it-02.js)

Constraints:

• The inputs start, stop, and step are integers.
• step is greater than 0.

Solution

node .guides/secure/getRangeWithStartAndStepTest.js

Problem 07

Problem Statement

You are tasked with creating a function named getExponentiations that returns an array of numbers. Each number in the array should be the result of raising the start value (which increments by the step value) to the power of exponent, with the sequence ending before reaching the stop value.

Your getExponentiations function should accept four parameters:

1. start: an integer representing the starting number.
2. stop: an integer representing the ending number.
3. step: an integer representing the interval between numbers.
4. exponent: an integer representing the power to which each number should be raised.

The function should return an array of integers representing the sequence of numbers based on the given parameters.

Here are some examples:

• getExponentiations(2, 10, 2, 2) should return [4, 16, 36, 64] because raising 2, 4, 6, and 8 to the power of 2 results in 4, 16, 36, and 64 respectively.

{Try It!}(node .guides/getExponentiations/try-it-01.js)

• getExponentiations(1, 5, 1, 3) should return [1, 8, 27, 64] because raising 1, 2, 3, and 4 to the power of 3 results in 1, 8, 27, and 64 respectively.

{Try It!}(node .guides/getExponentiations/try-it-02.js)

Constraints:

• The inputs start, stop, step, and exponent are integers.
• step is greater than 0.
