Suzuki needs help lining up his students!

Today Suzuki will be interviewing his students to ensure they are progressing
 in their training. He decided to schedule the interviews based on the length
 of the students name in descending order. The students will line up and wait
 for their turn.

You will be given a string of student names. Sort them and return a list of
 names in descending order.

Here is an example input:

string = 'Tadashi Takahiro Takao Takashi Takayuki Takehiko Takeo Takeshi Takeshi'

Here is an example return from your function:

 lst = ['Takehiko',
        'Takayuki',
        'Takahiro',
        'Takeshi',
        'Takeshi',
        'Takashi',
        'Tadashi',
        'Takeo',
        'Takao']

Names of equal length will be returned in reverse alphabetical order (Z->A) such that:

string = "xxa xxb xxc xxd xa xb xc xd"

Returns

['xxd', 'xxc', 'xxb', 'xxa', 'xd', 'xc', 'xb', 'xa']
