************pseudocode***********

take user input as string

convert string to lower case

create a list "ls" of words using split by whitespaces

initialise ls_letter[]....this will store letters

initialise ls_new[]

for words in ls..................loop through individual words
    for letters in words.........loop through individual letters in those words
        add letters to ls_letter

    retrieve first letter using slice and add it to a new list "y"
    delete the first letter from ls_letter
    append y[0] to ls_letter
    append "ay" to ls_letter

    join letters to create word using join()
    append newly created words to ls_new

    clear ls_letter tp process the next word

join the words seperated by space to form a new sentence using join()
print the sentence to screen
