[Ruby] On Split an array into half

2008-08-15T12:11:00-07:00

works for any size of the array

irb(main):001:0> column_1 = [1,2,3,4,5,6]
=> [1, 2, 3, 4, 5, 6]
irb(main):003:0> column_2 = column_1.slice!((column_1.size/2.0).round..column_1.size)
=> [4, 5, 6]
irb(main):004:0> column_1
=> [1, 2, 3]

thanks for the (artists.size / 2.0).round array and the enumeration idea

artists = [1, 2, 3]
column_1 = artists[0, (artists.size/2.0).round]
column_2 =  artists - column_1

The example works if the array has more than 2 elements - this is defect not a feature :)

    artists = [1, 2, 3]
    column_1 = artists[0..artists.size/2]
    column_2 = artists[artists.size/2+1..artists.size]
