Hi, i'm very new to Perl and I've been trying to implement a function that print out the line with the largest number. For example, If the input is:

Hello, i'm 18

1 this year is 2019 1

1 2 3 - 4

The output should beF 1 this year is 2019 1 

#!/usr/bin/perl -w

while ($lines = <STDIN>){
    @input = $lines =~ /\d+/g;
    @largest_number = sort {$a <=> $b} @$input;
    print "$lines\n";
}

I know that my code is crappy..I'm struggling with matching the digits in line and also the implementation of this function. Could someone please help me with it?

Another question is what does $line =~ /\-?(?:\d+\.?\d*|\.\d+)/g mean? Could someone please explain this line to me character by character? Appreciate for your help!
