Hello Monks. Your wisdom is needed! :) i have an array of many many way too many arrays. each element of every minion array is of various types, but the third element of every minion array in the master array is always a positive integer. this master array, i pass it to a function as a reference. i desperately need you to recommend the fastest way, with which, i can keep these three minion arrays of the master array, that contain the elements with the highest integers and discard the rest of the minion arrays... i.e.: 

my @masterArray = (
                  ["this", "that", 12563, "something", "else"],
                  ["this", "that", 10, "something", "else"],
                  ["this", "that", 1, "something", "else"],
                  ["this", "that", 125638, "something", "else"],
                  ["this", "that", 300000, "something", "else"],
                   );

subDiscarder(\@masterArray);

#
# AND THEN @masterArray should become:
#

@masterArray = (
                  ["this", "that", 300000, "something", "else"],
                  ["this", "that", 125638, "something", "else"],
                  ["this", "that", 12563, "something", "else"],
                );

being sorted is not of great importance. What is crucial, is the speed. I could figure out ways with foreaches and constant assignments of every element, but if there is a trully fast way to do it, or a module that can do this, i would appreciate it if someone could give me a hint towards there. thank you for your time. :)
