Accessing a hash in a hash

Ruby
1

Hello, I’m new to Ruby and am trying this example problem. I’m suppose
to have a hash key whose value is a hash.
Ex. hash[‘a’] => hash

Then, I’m suppose to change the second hash’s keys and values…

how do i go about this?

Hash1: Key => ( Hash2: aKey => aValue )

I want to change aKey and aValue

Hash1[key]???

How do I index it, or access it??

Thanks in advance!!!

Blind guess.

How about hash[key][key]
