WebYep, the examples match my expectations :) Some nits (I think most of these are basically just typos): upper_bound is still marked as returning Some; the descriptions for {lower,upper}_bound still state "If such an element exists it returns Some with the index of such element. Otherwise it returns None.".I would expect something like "If such an … WebBinary search Lower Bound and Upper Bound Now assume, the number you want to search from a particular list is present in that list more than one time. So in that case, … 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.
