in reply to Foreach loop

If you are going to use a for loop, I'd use something along the lines of ... 
my $keys = "5    10    14    16    17    20    25    26    38  1  42  
+  47    54";
my $substr = '1';
print "\nExist" if $_ eq $substr for split /\s+/, $keys;

Having said that, the OP has the whiff of homework

A user level that continues to overstate my experience :-))

    It might have the whiff of homework, but at least the OP posted functional code. It leaves us able to prod in the right direction without necessarily giving the whole house away.

    But yeah, some care was warranted. :-)
