I have this array:

[[16], [14], [13], [17], [18], [15, 16], [15, 14], [15, 13], [15, 17], [15, 18], [16, 14], [16, 13], [16, 17], [16, 18], [14, 13], [14, 17], [14, 18], [13, 17], [13, 18], [17, 18], [15, 16, 14], [15, 16, 13], [15, 16, 17], [15, 16, 18], [15, 14, 13], [15, 14, 17], [15, 14, 18], [15, 13, 17], [15, 13, 18], [15, 17, 18], [16, 14, 13], [16, 14, 17], [16, 14, 18], [16, 13, 17], [16, 13, 18], [16, 17, 18], [14, 13, 17], [14, 13, 18], [14, 17, 18]]

How do I remove some array brackets [] so that the array would be like: 

[16, 14, 13, 17, 18, [15, 16], ..., [14, 13, 18], [14, 17, 18]]

    this is not very elegant, but you will got what you want 🙂

    b = [[16], [14], [13], [17], [18], [15, 16], [15, 14], [15, 13], [15, 17], [15, 18], [16, 14], [16, 13], [16, 17], [16, 18], [14, 13], [14, 17], [14, 18], [13, 17], [13, 18], [17, 18], [15, 16, 14], [15, 16, 13], [15, 16, 17], [15, 16, 18], [15, 14, 13], [15, 14, 17], [15, 14, 18], [15, 13, 17], [15, 13, 18], [15, 17, 18], [16, 14, 13], [16, 14, 17], [16, 14, 18], [16, 13, 17], [16, 13, 18], [16, 17, 18], [14, 13, 17], [14, 13, 18], [14, 17, 18]]

b.collect { |c| c.count() ==  1 ? c[0] : c }
