3. Practice on LeetCode (Easy problems only)
   https://leetcode.com/

Focus On:

- Arrays
- Lists
- Stacks
- Queues
- Hash tables
- Big-O basics
- Searching and sorting


Learn Operating Systems Basics
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1. Operating Systems Overview (CrashCourse)

2. Linux Process Management (Hands-on)
   Use:
   - ps
   - top
   - htop
   - kill
   - chmod


When Done Should Be Able To:

-Explain what Big-O means

-Understand stack vs heap

-Explain how processes run

-Understand how memory is allocated

-Explain why buffer overflows happen



Practice Ideas
=================

-Implement a stack and queue in Python

-Write a small program that measures runtime differences

-Use chmod to change file permissions and explain what changed

-Use ps and top to monitor running processes
