WebIf A is the array and N is the number of items in the array, the item could be anywhere from A[0] to A[N-1]. And most textbooks teach binary search using two variables, the lower bound and upper bound, for that range of indices. And they use L=0 and U=N-1. The upper bound, U, is an inclusive upper bound because N-1 is a valid element.
