I have an array of elements. If I do a arr.max I will get the maximum value. But I would like to get the index of the array. How to find it in Ruby
For example
a = [3,6,774,24,56,2,64,56,34]
=> [3, 6, 774, 24, 56, 2, 64, 56, 34]
>> a.max
a.max
=> 774
I need to know the index of that 774 which is 2. How do I do this in Ruby?
