I am doing questions from different sites. I came accross this one, not sure how to go about it There are 2 csv files that have following information File 1:
Application Memory (GB) Language
App1 4 Perl
App2 8 Java
App3 8 Java
App4 4 PHP
App5 8 C#

File 2:
Application CPU Cores
App1 1.5 2
App2 2.5 4
App3 2.8 4
App4 2.8 2
App5 2.8 2
Need to print name of apps that have CPU value 2, sorted by their memory size e.g App1, App4 and App5 I was thinking of using nested hash to read the file elements 
my %apps;
$apps{"App1"}{Memory}   = 4;
$apps{"App1"}{Language}    = 'Perl';
$apps{"App1"}{CPU}    = '1.4';
$apps{"App1"}{Cores}    = '2';

[download]
.... So on. Is this the right way to read file into nested hash ? Not able to wrap my head around the problem
