Binary Search
by Anonymous
Compare linear search, binary search, and direct lookup to see how far the number of tries drops.
About this app
Binary Search is an interactive coding-basics lesson that compares three ways to find an item: scanning one position at a time, repeatedly halving a sorted list, and using labels to jump directly to a position. Learners complete guided challenges, count how many looks each method takes, and see why ordering or labels can greatly reduce search effort.
