WebBinary search is an inherently recursive algorithm: we can implement iteratively, but it makes more sense algorithmicly to do it recursively (though for certain implementations you might choose to do it iteratively for efficiency reasons). Binary search works by splitting up a sorted data set into two parts. WebThe recursive implementation of binary search is very similar to the iterative approach. However, this time we also include both start and end as parameters, which we update at each recursive call. The pseudocode for a recursive binary search is shown below. function BINARYSEARCHRECURSE (ARRAY, VALUE, START, END) (1) # base case if …
