Fom additional material given and complete the function myBinSearch, which should implement a binary search algorithm on a sorted array. Parameter is on the one hand the search element to be looked for and on the other hand a reference to the array, where to look for the search element. If the search element is part of the array, myBinSearch should return the position of the found element, otherwise 1 should be returned. If you have finished, execute the prepared script and look whether the test cases give the correct results. [Consider: The algorithm may be only applied to a sorted array, where the sorting criterion should be the same criterion as used for decisions in binary search]. use strict; use warnings; sub myBinSearch { my $refToSortList=$_[0]; my $search=$_[1]; #Complete } my @testList = (254324, 213, 2345, 6524, 3475, 81451, 1141); my @perlSort = sort { $a <=> $b } @testList; print "\n\n\n"; print "perlSort1: ", join(" ", @perlSort), "\n"; print "\n\n\n"; #Check binary search on sorted array print "Binary Search:\n"; foreach my $entry (@perlSort){ print $entry1, ": ", myBinSearch(\@perlSort, $entry1), "\n"; print $entry, ": ", myBinSearch(\@perlSort, $entry), "\n"; print $entry+1, ": ", myBinSearch(\@perlSort, $entry+1), "\n"; } print "\n";
