Hello All,
I have some simple files to parse. The data looks like this:
54 6342059
80 6342059
31 6158566
54 6158566
80 6158566
31 6341718
54 6341718
80 6341718
31 6341743
54 6341743
54 6341743
80 6341743
31 6341714
54 6341714
54 6341714
80 6341714
31 6188293
54 6188293
54 6188293
80 6188293
54 6713711
80 6713711
54 6713712
80 6713712
54 6489814
80 6489814
54 6713889
80 6713889
54 6713793
54 6713793
80 6713793
The first column is an activity code and the second column is a client id
number.
Here is my task. I need to find the number of unique individuals that
participated in each activity. Now the boring, tedious way would be to write
something like this:
for my $row {
$act_54{$row1} if (column1 == "54");
$act_80{$row1} if (column1 == "80");
$act_90{$row1} if (column1 == "90");
}
print scalar (keys %act_54);
print scalar (keys %act_80);
print scalar (keys %act_90);
Surely, there is something that will capture the data a little easier than
defining a variable for each activity. There are more than 30 activities.
Thank you for your help.
Elton
