How do I find .index of a multidimensional array

Question

Tried web resources and didnt have any luck and my visual quick start guide.

If I have my 2d/multidimensional array:

 array = [[\'x\', \'x\',\' x\',\'x\'         


        

Answer 1

This will do it:

array = [['x', 'x',' x','x'],
         ['x', 'S',' ','x'],
         ['x', 'x',' x','x']]

p array.index(array.detect{|aa| aa.include?('S')}) # prints 1

If you also want 'S's index in the sub array you could:

row = array.detect{|aa| aa.include?('S')}
p [row.index('S'), array.index(row)] # prints [1,1]
