Hi, I've searched the internet on how to handle duplicate keys in a hash, but am still confused. For instance, take a text file with numbers on the left, names on the right, with numbers as keys, names values.

1 AAA

2 BBB

3 CCC

4 DDD

2 EEE

From what I've read, you're supposed to use hash references into arrays? But I don't see how(in example) typing in the "2" would pull up both BBB AND EEE when the info is embedded within a reference within a hash, if this is the correct way to go about it. What is the simplest method to approach the duplicate key problem? Any clarification you might offer will be greatly appreciated. <\p>
