They have a very strange money system in Byteland. Each Byteland gold coin has a whole number written on it. Coin n can be exchanged at the bank for three coins: n/2, n/3 and n/4. But these numbers are all rounded down (banks have to make a profit). You can also sell Byteland Coins for US Dollars. The exchange rate is 1:1. But you cannot buy Byteland coins. You have one gold coin. What is the maximum US dollar amount you can get for this? Note: Please answer the question in Python only: Output 13 2 Input 12 2
Write a Python program in a Linux/UNIX script called myprogram.py. Write a Python program that continuously (i.e., in an infinite loop) asks the user for a number m. At each iteration of the loop, check in parallel whether m is greater than 10, greater than 20, and greater than 30. Make sure that the three comparisons may be performed in parallel (i.e., so that the three outputs can theoretically be printed in any order). Use the smallest number of processes. Make sure you don’t create zombie processes. Use the code below as a template. Use this template: from os import wait,waitpid,fork # write your code here while (True): #make sure to indent this and the next lines m=float(input('Give me a number: ')) # your code here

Write a python program that takes a string as an input from the user and then modifies the string in such a way that the string always starts with an uppercase letter and the case of each subsequent letter is the opposite of the previous letter (uppercase character followed by a lowercase character followed by an uppercase character and so on). Finally the modified string is printed to show the user.
