in thread Fastest way to compare multiple variables?

Try this:

#!/usr/local/bin/perl -w use strict; my @list=("abcd123","abcd143","abcd123","abcd123"); $_=join("",@list); s/$list[0]//g; print "not equal\n" if ($_);

    The problem with that is that the code will produce an incorrect result in the case:

    my @list={"a","aaaa","aa","aaaaaaaa","a"};

    In the above (admittedly pathological) case, it would report all equal when this is not true.

      I love Perlmonks. ;-)
