Question

I have an array like (“valueA”, “valueB”, “valueC”, “valueD”) etc. I want to loop over the values of the array starting from (for example) the first instance of “valueC”. Everything in the array before the first instance of the value “valueC” should be ignored; so in this case only “valueC” and “valueD” would be handled by the loop.

I can just put a conditional inside my loop, but is there a neater way to express the idea using perl?

Answer 1

my $seen;
for ( grep $seen ||= ($_ eq "valueC"), @array ) {
    ...
}
