Hi All,
I wasn't sure if there is an easy way to do what I am trying to do and I was not able to find anything on google. When I use excel I am able to sort by one column and then by another column and so on, but with perl instead, of course... For example I have a two-dimensional array '@test' that looks like the following. 1 3 5 6 2 3 4 5 6 7 1 2 3 4 5 5 6 7 8 8 1 2 3 4 5 2 2 2 2 2 1 1 2 4 5 2 3 4 5 6 I would like to make a sub that would allow me to pass in the array and the columns that I want to sort and the the sub output the sorted array by to @test. Basically pass @test into the sub and sort by column 1 then 2 then 4. &sortSub(@test, 1, 2, 4); after the sort 1 1 2 4 5 1 2 3 4 5 1 2 3 4 5 1 3 5 6 2 2 2 2 2 2 2 3 4 5 6 3 4 5 6 7 5 6 7 8 8 Does anyone know of an easy way to do this? Does anyone happen to have a routine that already does this?
After all this is over, all that will really have mattered is how we treated each other.
