WebSet m (the position of the middle element) to the floor (the largest previous integer) of (L + R) / 2. If Am < T, set L to m + 1 and go to step 2. If Am > T, set R to m − 1 and go to step 2. Now Am = T, the search is done; return m. This iterative procedure keeps track of the search boundaries with the two variables.
