Ok, I'll try but my English is not good at all.
Perl switches (perldoc perlrun):
"-n" reads lines from @ARGV (that is INPUTFILE) to $_ and "-l" removes and adds (when printing) newline chars. "-a" splits $_ to @F array according to a regex from "-F" option
"grep {! RE} @F" filters all elements from the array (elements are strings - "{123, 0, 111}" and so on) where it's not true that 0 is a "word" (not in any numbers like 10, 101, etc.).
Then we join the ready list to a string with ", " as the separator and print it.
