### Skill #1: Writing a for-loop

def product(nums):
    """
    Takes in a list of integers, and returns the product
    of all of them multiplied together.

>>> nums = [1, 2, 100]
    >>> product(nums)
    200

>>> nums = [1, 2, 100, 2, 3, 0]
    >>> product(nums)
    0

>>> nums = [-1, 2, 10, 5]
    >>> product(nums)
    -100
    """
    # YOUR CODE GOES HERE

def adjust(nums):
    """
    Takes in a list of integers and adds the index of each element
    to itself. Ex: [10, 10, 10] -> [10, 11, 12]
    
    >>> nums = [10, 10, 10]
    >>> adjust(nums)
    [10, 11, 12]

>>> nums = [1, 2, 3, 4, 5]
    >>> adjust(nums)
    [1, 3, 5, 7, 9]
    """

### Skill #2: Writing a while-loop

def factorial(n):
    """
    Return the factorial of n, where n >= 1.

>>> factorial(1)
    1
    >>> factorial(4)
    24
    """
    # YOUR CODE GOES HERE

### Skill #3: Writing a conditional (if/elif/else) logic

def change(num):
    '''
    Return a number based on the following:
    - if num is positive and odd,
    return the number multiplied by 2
    - if num is positive and even,
    return the number multiplied by 3
    - if num is non-positive, 
    return the number as it is

>>> change(3)
    6
    >>> change(-100)
    -100
    '''
    # YOUR CODE GOES HERE

def grade_detector(grade):
    """
    Return a student's grade based on their score.
    Grading scale as follows (inclusive):
    - 'A': 90+
    - 'B': 80-89
    - 'C': 70-79
    - 'D': 60-69
    - 'F': Below 60

args:
        grade (int): grade input
    returns:
        the corresponding letter grade of the grade
        
    >>> grade_detector(95)
    'A'

>>> grade_detector(82)
    'B'

>>> grade_detector(58)
    'F'
    """
    # YOUR CODE GOES HERE

### Skill #4: Writing a loop with conditional statements inside

def even_counter(nums):
    """
    Return the number of even numbers in the list

>>> nums = [1, 2, 3, 4, 5]
    >>> even_counter(nums)
    2

>>> nums = [22, 44, 66, 21]
    >>> even_counter(nums)
    3
