Algorithms: Final Steps
The finale of the Algorithms series: we gather everything we learned in nine posts (variable, conditional, loop, list, function, dictionary), combine it in one program, and point to the next step.

Algorithms: Functions
What is a function and how do you define a job once and call it by name again and again? Learn parameters, RETURN, the black box and local variables — no code.

Algorithms: Lists
What is a list and how does a computer store many values under one name? Learn indexes, walking a list with a loop, and the count-from-zero trap — no code.

Algorithms: Loops
What is a loop and how does a computer repeat the same work? Learn counter and conditional loops, a loop's three parts and the infinite-loop trap — no code.

Algorithms: Conditionals
What is a conditional (IF-THEN) and how does a computer decide? Learn single, double & multi-branch conditions, AND/OR/NOT logic and nested decisions — no code.

Algorithms: Flowcharts
What is a flowchart and how do you draw one? Learn an algorithm's three building blocks — sequence, decision and loop — step by step, with examples and no code.

Algorithms: Pseudocode
What is pseudocode and how do you write it? The bridge from flowchart to code: assignment, conditionals, loops, comparison and logic operators.

Algorithms: Variables
What is a variable and how does a computer store data? Learn value assignment, operations, data types and naming via the labeled-box analogy.
