Re: TIMTOWTDI Challenge: Zero'ing Out An Array

in reply to TIMTOWTDI Challenge: Zero'ing Out An Array

No map??

map{pop@array}@array

Late addition:

{pop@array&&redo}

[Corion]

That won't work if the array contains a zero or an empty string:

> perl -wle "{pop@ARGV && redo}; print for @ARGV" 1 2 0 4 5
1
2

A fix would be to check @ARGV:

> perl -wle "{pop@ARGV,@ARGV && redo}; print for @ARGV" 1 2 0 4 5

... possibly with aliasing @_ to the array:

> perl -wle "{local *_=\@ARGV; pop && redo}; print for @ARGV" 1 2 0 4 
+5
