Arithmetic Algorithms and String Processing

Apply while loops, modulo operations, the Euclidean algorithm, and string slicing to solve practical problems.

Objectives

Calculate GCD and LCM using the Euclidean algorithm
Check for prime numbers more efficiently than testing every divisor
Normalize strings before checking for palindromes

This lesson is for Pro members

Small algorithms like Euclid's or prime checking are excellent exercises for sharpening your logic regarding loops, termination conditions, and optimizing processing steps.
