Ruby: how to know depth of multidemensional array
- by hqt
This is my problem I have met in my assignment.
Array A has two elements: array B and array C.
Array B has two elements: array D and array E
At some point, array X just contains two elements: string a and string b.
I don't know how to determine how deep array A is. For example:
arrA = [
[
[1,2]
]
]
I have tested by: A[0][0][0] == nil which returns false. Moreover, A[0][0]..[0] == nil always returns false. So, I cannot do this way to know how deep array A is.
