WebAnalysis. Linear search runs in O (n) time. Whereas binary search produces the result in O (log n) time. Let T (n) be the number of comparisons in worst-case in an array of n elements. Hence, T ( n) = { 0 i f n = 1 T ( n 2) + 1 o t h e r w i s e. Using this recurrence relation T ( n) = l o g n. Therefore, binary search uses O ( l o g n) time. WebRecursive Binary Search.

WebJul 27, 2024 · In a binary search algorithm, the array taken gets divided by half at every iteration. If n is the length of the array at the first iteration, then at the second iteration, the length of the array will be n/2. Again dividing by half in the third iteration will make the array’s length = (n/2)/2=n/ (2^k). WebBinary search is an efficient algorithm for finding an item from a sorted list of items.
