WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. Compute guess as the average of max and min, rounded down (so that it is ...
