Write a python program that implements a text$-$based menu. The menu should present the user with the following $4$ choices:

$$ Option $1$: Append data to the input buffer

o This option will prompt the user for a string and append it to any previous input that has been provided.

$$ Option $2$: Clear the input buffer

o This option will clear any data that has been previously input.

$$ Option $3$: Display the input buffer

o This option will print to the screen whatever input data is currently being saved.

$$ Option $4$: Exit the program
