Lesson 3-Problem Solving

PART 1- Worked Solution

The Tile Problem

Solving problems by hand is the first step in being able to write your own programs. In this example we define a problem, work through the solution and then show how an algorithm is created using the solution, and present the final python code.

Part 2 - Adapt the Solution

Modify the program that there are now 3 tile colours, [Black, Grey, White]. Remember, the first and last tile should always be black. Click on the instructions table for more information.

PART 3 - Exercise 1

The Robot Problem

In this challenge we present a problem and provide you with all of the information you need to solve it by hand, and to produce an algorithm which can then be coded in python.
