Count along with us! A first numbers lesson for little learners.
Big O notation describes how an algorithm's cost grows as the input grows. O(N) means doubling the input doubles the work. O(N²) means doubling the input quadruples the work. This lesson builds Big O intuition through programming examples, comparison tables, & hands-on cost calculations — then points to a deeper dive in our unhamming course.
Big O describes worst-case growth. Theta describes tight bounds. Omega describes best case. Space complexity tracks memory, not just time. Amortized analysis spreads occasional expensive operations across a sequence. This lesson builds the formal toolkit for analyzing any algorithm.
A list stores items in order. A set stores unique items for instant lookup. Choosing between them changes your program from O(N²) to O(N). This lesson builds intuition for when to reach for each data structure, how their Big O costs differ, & how to combine them to solve real problems.
Algorithms live everywhere: in how you sort your toys, find your shoes, or figure out the fastest way to eat your vegetables first. This lesson finds algorithms in everyday life, sorts by color & size, & discovers that some ways of searching work faster than others.
Linear search checks every item one by one. Binary search jumps to the middle & cuts the work in half each time. Bubble sort compares neighbors & swaps them. This lesson builds intuition for why organized data lets computers work faster — with hands-on examples using numbers & words.
