Binary search time complexity calculation

WebBinary Search is a searching algorithm for finding an element's position in a sorted array. In this approach, the element is always searched in the middle of a portion of an array. … WebBinary search has a worst-case time complexity of O(log n), while linear search has a worst-case time complexity of O(n). This means that as the size of the array increases, the efficiency advantage of binary search over linear search becomes more pronounced. Therefore, for larger arrays, binary search is almost always the preferred algorithm ...
