Given this string of words:

name $=$ 'George Herbert Walker Bush'

write a program that rotates the words in the string, such that for each rotation, the words that was last is now first.

Details:

Write two user defined functions.

The first function, called last$2$first, will take a multi$-$word string as argument and move the last word in a multi$-$word string to the beginning of the string, and then return the string

So for example, if passed the string

George Herbert Walker Bush

the function will return

Bush George Herbert Walker

The second function, called rotate, will use repetition to call the last$2$first function to rotate the words in the string, such that for each rotation, the words that was last is now first. The rotate function will print the string returned by the last$2$first function.

The rotation should continue calling the last$2$first function until the word has been completely rotated, printing each rotation as it goes.

The calling code is as follows:

pres $=$ 'George Herbert Walker Bush'

rotate$($pres$)$

The output will look like this:

George Herbert Walker Bush

Bush George Herbert Walker

Walker Bush George Herbert

Herbert Walker Bush George

There are plenty of ways to do this in Python. A simple solution can be constructed using these list and string methods:

split

pop

insert

join
