hi all
i have 2 array one is refernce array where as other array is generated from text file. array A has all letters from A-z and a-z and i want to find out which letters are missing in generated array and push them in another array to display them.
i have following code ....
for my $ref (@reference) { #this is reference array
if ( ! grep $ref, @no ) # @no is generated array
{
push @usable, $ref ; # @usable array to store unused letters
}
}
this code prints no usable letters even when there are ...can u tell where i m doing wrong ?
