Write a program that creates three threads. The first thread will ask the user to enter a string, the second thread will also ask the user to enter another string and the third thread must find the shared letters between both strings and insert them into a list called shared_letters, then print the list. Please note that the strings are case sensitive, meaning that A doesn't equal to a etc. You must use either python global variables or a Queue
