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.
