Hash - Min and Max values

[bigbalbossa]

A delimited flat file contains two fields: List Number and Seq Number.

1|1
1|2
1|3
1|4
1|5
2|1
2|2
2|3
2|4
2|5

I need to find the min and max value for each list number. Seems easy enough...but i'm struggling.

Thanks All.

do you need to find if $1 >|< $2 line per line or do you need to find out the over all min and max values for the left fields, and the left min and max fields?

 

[NateBro]

ok do you need to return list number 1 min = 1; max = 5; and list number 2 min = 1; max = 5;?

 

[bigbalbossa]

Exactly. I need to print:

List 1 - Min = 1 Max = 5
List 2 - Min = 1 Max = 5

Or something similar

This should be simple, what have you tried so far?

ok, do you already have a script that reads the file and puts them into a var $secular, %hash or @array? if you already do just post your code you have so far and I'll put it together.

I got it fellas. Wasn't difficult after i got some sleep

The code snippet above was simplified from my script. I was working with a hash of a hash...this worked:

$hash{$LIST_NUM}{FileSeqNum}=$FileSeqNum;
