Write a python program which asks for a string of data. It will code the data by substituting some of the characters. Make it as complicated as possible! Here are some ideas:

a$.$ Make the first character uppercase

b$.$ Replace vowels with the next one. $A$ is replaced by $E,E$ by I etc.

c$.$ Replace all occurrences of $S$ or $s$ with $

d$.$ Replace all numbers $1-4$ with double the number

Example:

password$1234$ would become Pe$$wurd$2468$
