;Task:
Given a prompt and a list containing a number of strings of which one is to be selected, create a function that:
* prints a textual menu formatted as an index value followed by its corresponding string for each item in the list;
* prompts the user to enter a number;
* returns the string corresponding to the selected index number.
<br>
The function should reject input that is not an integer or is out of range by redisplaying the whole menu before asking again for a number. The function should return an empty string if called with an empty list.
For test purposes use the four phrases: “<tt>fee fie</tt>”, “<tt>huff and puff</tt>”, “<tt>mirror mirror</tt>” and “<tt>tick tock</tt>” in a list.
For test purposes use the following four phrases in a list:
fee fie
huff and puff
mirror mirror
tick tock
