Module 1: Technical Preparation: Review of Basics

Module 1 focuses on reviewing fundamental programming concepts. You'll refresh your knowledge of functions, variables, and basic math operations in Python.

Function Review

This section covers:

• Creating and calling functions
• Working with function parameters
• Return values and their importance
• Function scope and variable access

Variable Review

Learn about:

• Variable declaration and assignment
• Naming conventions and best practices
• Variable scope and lifetime
• Common variable operations

Math Review

This section reviews:

• Basic arithmetic operations
• Order of operations (PEMDAS)
• Common mathematical functions
• Working with numeric data types

In the guided project, you'll practice using LeetCode to solve basic programming challenges. First, you should register for a free LeetCode account. This will help you become familiar with the platform while reinforcing your understanding of functions, variables, and mathematical operations.

Recommended LeetCode Problems

Note: For all problems, you can select Python as your programming language using the dropdown menu in the LeetCode code editor.

• Two Sum - Apply basic variable manipulation
• Palindrome Number - Practice math operations and logic
• Add Two Integers - Simple function practice
• Fibonacci Number - Function implementation with math concepts
• Number of Steps to Reduce a Number to Zero - Practice with math operations and functions
• Subtract the Product and Sum of Digits of an Integer - Practice with math operations
• Count Odd Numbers in an Interval Range - Apply math logic

To reinforce your understanding of the concepts covered in this module, complete the following activities:

• Create a free LeetCode account if you haven't already
• Complete the setup and familiarize yourself with the LeetCode coding environment
• Choose and solve at least 5 problems from the recommended list above
• For each problem:
  • First try to solve it without looking at hints
  • If you get stuck, use the Hints feature (available on most problems)
  • After solving, consider reviewing the Discussion section to see how others approached the problem
• Consider practicing debugging by intentionally creating errors in your solutions and fixing them
