Assume the variable $f$ irst is assigned a string that is a person's first name, and the variable last is assigned a string that is a person's last name.

Write a statement that assigns to the full$\_$ name variable the person's full name in the form "Last, First". So$,$ if first is assigned "alan" and last is assigned "turing", then full$\_$ name would be assigned "Turing,Alan". $($Note the capitalization! Note: no spaces!$)$ And if first and last were "Florean" and "fortescue" respectively, then full$\_$ name would be assigned "Fortescue,Florean".
