$110,$ write a program that prints a secret message hidden in a list of integers entered by a spy ($($user),$),$ provided the list of integers is secure.$.$ The user will input a list of integers that could be as long as 50,000$50,000$ integers. Each integer is between 65$65$ and 90$90$ inclusive and represents a capital letter in ASCII. However, for improved security, the secret message to be printed consists of every second integer starting with the first integer. The input is secure if the sum of all input integers is a prime number. If the message is secure,$,$ print the hidden message and quit the program; otherwise, quit the program. Prompt the user to enter the total number of integers in the message.
