Question

Define a function group-by-nondecreasing, which takes in a stream of numbers and outputs a stream of lists, which overall has the same numbers in the same order, but grouped into segments that are non-decreasing.

Answer 1

Answer:

def group_by_nondecreasing( *args ) :

     num_list = [arg for arg in args]

     sorted_numlist = sorted( num_list )

     list_stream = [ sorted_numlist, sorted_numlist, sorted_numlist ]

     return list_stream

Explanation:

This python function has the ability to accept multiple and varying amount of arguments. the list comprehension shorten the logical for statement to generate a list of numbers, sorts the list in ascending order by default and duplicates the list in another list.
