$(20$ marks$)$ Write a function swapper$()$ that takes in a string as a parameter and then asks the user for a number between $1$ and two less than the number of characters in the string. Then construct two strings that split the input string at the number specified by the user. Finally, create a new string by swapping the new strings and return the result.

For instance, if the input word is $$elephant$$ and the computer must ask the user to input a number between $1$ and $6.$ If the number of user inputs is $3,$ then the two new strings become $$ele$$ and $$phant$.$ The return string becomes $$phantele$.$ Assume the string has more than three characters.

Usage with another example is given below:

$>>>$ swapper$(\text{'}$england$\text{'})$

Enter a number between $1$ and $5$: $4$

'andengl'

$>>>$ swapper$(\text{'}$illinois$\text{'})$

Enter a number between $1$ and $6$: $6$

'isillino'
