Write a function larger_decrement(numlist, n) that takes two parameters, a list of integers numlist, and an integer n.

Question

Documentation: 

Use the following template for EVERY function that you write. The docstring below should be placed inside of the function, just after the function signature.

'''

Purpose:

Parameter(s):

Return Value:

'''

If the given list contains any number larger than n, then have the function mutate the list by decreasing the largest item in the list by 1. If the list has two or more elements tied for the largest, only decrease the first occurrence. Then the function should return True. 

If the given list does not contain any number larger than n, it should return False.

Examples (text in bold is returned):

>>> alist = [5, 20, 74, 81, 0, 81, 3]

>>> larger_decrement(alist, 50)

True

Answer 1

Here is an example implementation of the function larger_decrement(numlist, n) in Python:

def larger_decrement(numlist, n):

  """

  Given a list of integers numlist and an integer n, returns a new list with each element decremented

  by n if the element is greater than or equal to n, otherwise returns the original element.

  """

  newlist = []

  for num in numlist:

    if num >= n:

      newlist.append(num - n)

    else:

      newlist.append(num)

  return newlist

The 'larger_decrement'() function takes two parameters, 'numlist' and 'n', where 'numlist' is a list of integers, and 'n' is an integer. The function creates a new empty list 'newlist' and then iterates through each element in 'numlist'.

For each element, the function first checks if the element is greater than or equal to 'n'. If it is, the function decrements the element by 'n' and appends the result to 'newlist'. If the element is less than 'n', the function simply appends the original element to 'newlist'.

Finally, the function returns 'newlist', which contains the updated elements.
