1.Astronomy Helper Create an application that displays the following menu: Select a Planet
_1. Mercury
- Venus
- Earth
- Mars
- Exit the program Enter your selection._ When the user selects a planet from the menu, the program should display data about the planet’s average distance from the sun, the planet’s mass, and the planet’s surface temperature. 2. Password Weakness Detector Design a program that asks the user to enter a password, and then analyzes the password for the following weaknesses:
- Fewer than 8 characters
- Does not contain at least one uppercase letter and one lowercase letter
- Does not contain at least one numeric digit
- Does not contain at least one special character (a character that is not a letter or a numeric digit)
- Is a sequence of consecutive uppercase letters (such as ABCDE)
- Is a sequence of consecutive lowercase letters (such as abcde)
- Is a sequence of consecutive numeric digits (such as 12345)
- Is a repeating sequence of characters (such as ZZZZZ or 55555) The program should display messages indicating whether any of these weaknesses are found in the password. 3. Recursive Power Method Design a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer.
