WebAug 5, 2012 · Runtimes can be described with mathematical functions. For an array of size n, linear search runtime is a linear function, and binary search runtime is a function of log base 2 of n (or log n + 1 comparisons). This is called the big-O runtime function in computer science, for example O(log n) vs. O(n). WebOct 13, 2024 · I am learning about AVL trees. AVL trees are Binary Search Trees that balance themselves through rotations. Because they are balanced, the query time is O(log n).
