You take first element do a constant work i.e. compare it to k and then you proceed with the remaining size n-1. If you have only one element, it is T (1) = 1 only one comparison. Share WebA recursive approach to linear search rst searches the given element in the rst location, and if not found it recursively calls the linear search with the modi ed array without the rst element. i.e., the problem size reduces by one in the subsequent calls.

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.
