Chapter 18.3, Problem 18.3.3CP
Program Plan Intro
Recursive method:
A method which is called again and again by itself is called as recursive method. With the help of recursive method, it is possible to solve certain problems more quickly and easily.
Pros and cons of recursion:
Pros: recursion reduces unnecessary calling of functions. It is possible to solve complex problems more easily.
Cons: Recursion is always logical which is very difficult to understand. It takes more stack space. It also takes more time to process.

1. Draw flow charts for each of the following;a) A system that reads three numbers and prints the value of the largest number.b) A system reads an employee name (NAME), overtime hours worked (OVERTIME), hours absent(ABSENT) and determines the bonus payment (PAYMENT).
Scenario
You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement.
You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds.
The conversions are as follows:
1 kilogram = 35.274 ounces
1 kilogram = 2.20462 pounds
1 pound = 0.453592 kilograms
1 pound = 16 ounces
1 ounce = 0.0283 kilograms
1 ounce = 0.0625 pounds
For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…
