WebBinary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one. We used binary search in the guessing game in the introductory tutorial.

WebOct 4, 2024 · The time complexity of the binary search algorithm is O (log n). The best-case time complexity would be O (1) when the central index would directly match the desired value. Binary search worst case differs from that. The worst-case scenario could be the values at either extremity of the list or values not in the list. WebThe best case of Binary Search occurs when: The element to be search is in the middle of the list In this case, the element is found in the first step itself and this involves 1 … WebFeb 6, 2024 · The best-case time complexity is [Big Omega]: O (nlogn). It is the same as average-case time complexity. Space Complexity Space Complexity for this algorithm is O (n) because n nodes have to be created for each element inside the binary search tree.
