Solving Recurrences Example - Binary Search (Master Method)

WebThe key idea is that when binary search makes an incorrect guess, the portion of the array that contains reasonable guesses is reduced by at least half. If the reasonable portion had 32 elements, then an incorrect guess cuts it down to have at most 16. Binary search halves the size of the reasonable portion upon every incorrect guess.

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.
