WebJan 11, 2024 · Linear or Sequential Search. This algorithm works by sequentially iterating through the whole array or list from one end until the target element is found. If the element is found, it returns its index, else -1. Now let's look at an example and try to understand how it works: arr = [2, 12, 15, 11, 7, 19, 45] Suppose the target element we want ... WebJun 18, 2024 · Huffman coding is the foundation of modern text compression. It works by considering how often different characters appear in a text, and organizes them in a tree based on this frequency. 5. Breadth First Search Again, trees turn out to be at the heart of a lot of algorithms and software that developers work with.
