Amazingly, this simple task doesn't seem to exist already, so... Your task is to write a program that takes as input a 12 hour time, and converts it into "military time", or 24-hour time format. Input will be in the form: HH:MM am/pm Although slight variations are allowed: The space separ...

Challenge: Create a program that accepts a positive integer and checks if it can be written in the form of (3^x)-1, where X is another positive integer. If it can, output X If it can't, output -1 or a falsy statement. Example inputs/outputs Input: 2 It can be written as (3^1) - 1, so we o...
