WebHere is modified pseudocode for binary search that handles the case in which the target number is not present: Let min = 0 and max = n-1. If max < min, then stop: target is not present in array. Return -1. Compute guess as the average of max and min, rounded down (so that it is an integer). If array [guess] equals target, then stop. You found it!

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. maangchi cinnamon rolls ma and pa\u0027s restaurant indianapolis
