Pseudocode
Also known as: pseudo code, structured English
An informal, human-readable description of an algorithm using structured language that resembles code but isn't tied to any specific programming language. Writing pseudocode before coding reduces errors, clarifies thinking, and makes it easier to communicate algorithms to others.
💡 Intuition
Pseudocode is a rough draft for code — write the logic in plain English first, then translate to real code.
Core Idea
Pseudocode lets you focus on logic without worrying about syntax. It's a planning tool, not a running program.
🔬 Example
🎯 Why It Matters
Writing pseudocode before coding reduces errors, clarifies thinking, and makes it easier to communicate algorithms to others.
⚠️ Common Confusion
There's no single 'correct' pseudocode format. It just needs to be clear and unambiguous to the reader.
