I am currently creating a Ruby program and have run into an issue that I am unable to solve.

I have an array of hashes that holds a lot of the information in my program. For example:

array = [{ name: "Jack", gender: "Male", age: 30 }, { name: "Wendy", gender: "Female", age: 42 }, { name: "Julie", gender: "Female", age: 29 }]

I know that I can access the individual hashes like so:

array.each do |person|
   puts person[:age]
end

What I am trying to achieve is to find out which value of the 'age' key is the highest, and then assign that age to a variable called 'highest_age'

I have been trying something like this:

age = array.select { |person| person[:age] }
highest_age = age.max

This is not working for me. Can anybody help at all? Would appreciate any help.

The result should be that the 'highest_age' variable contains the integer 42 as that is the highest age of the three ages I have in my array.

Thanks in advance
