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! WebC++ Algorithm binary_search () function is used check whether the element in the range [first, last) is equivalent to val (or a binary predicate) and false otherwise. The range [first, last) must satisfy all of the following conditions: Partitioned with respect to element < val or comp (element, val).
