Answer 1

To create a program that asks for a username and password and performs input validation.

Step-by-step explanation:

To create a program that asks the user for a username and password, you can use a loop to continue asking for inputs until the user enters correct values. To perform input validation, you can utilize regular expressions or string manipulation. For the username, you can use regular expressions to check that it only contains letters and numbers and doesn't start with a number. For the password, you can use string manipulation to check for the presence of at least one non-numeric or alphabetic character, at least one uppercase letter and one lowercase letter, at least one number, and that it doesn't contain three of the same letters in a row.
