Practice Pseudocode in CS Thinking

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

An informal, human-readable description of an algorithm using structured language that resembles code but is not tied to any specific programming language. Pseudocode uses plain English mixed with programming constructs like IF, WHILE, and FOR to describe logic without worrying about syntax rules.

Pseudocode is a rough draft for code — write the logic in plain English first, then translate to real code.

Example 1

easy
Write pseudocode for a program that asks the user for two numbers and outputs the larger one.

Example 2

medium
Convert the following Python code to pseudocode: total = 0; for i in range(1, 11): if i % 2 == 0: total += i; print(total).

Example 3

medium
Write pseudocode for a program that reads a list of 10 numbers and outputs how many are above average.

Example 4

hard
A colleague writes pseudocode that mixes Python syntax, uses unclear variable names, and skips steps. Identify three problems with: 'x = input(); for y in x: if y == z: cnt+=1; print(cnt)'. Rewrite it properly.
