Average case analysis of binary search

★ ★ ☆ ☆ ☆

The average cost of a successful search is about the same as the worst case where an item is not found in the array, both being roughly equal to logN. So, the average and the worst case cost of binary search, in big-O notation, is O(logN).

Binary search algorithm - Wikipedia

★ ★ ★ ☆ ☆

Binary search runs in logarithmic time in the worst case, making O (log n) comparisons, where n is the number of elements in the array, the O is Big O notation, and log is the logarithm. Binary search takes constant (O (1)) space, meaning that the space taken by the algorithm is the same for any number of elements in the array.
