Question

I have created several arrays, containing multiple integers. Now i want the integers to be sorted, lowest first. Say for instance, i have this in an array: 6,6,1,2,4,4, i want it to be sorted: 1,2,4,4,6,6. Also, is there anyway i can make ruby recognize the 4 lowest values, and display them somehow? I have tried to mess around with .show, but since im quite new to programming i’m rather confused by the results i receive.

Answer 1

did you try this?

a = [6,6,1,2,4,4]

p a.sort
#=> [1, 2, 4, 4, 6, 6]

sort will sort in ascending order.

if you need them sorted in descending order, use sort with a block:

p a.sort {|a,b| b <=> a}
#=> [6, 6, 4, 4, 2, 1]

UPDATE: not sure how i missed the part about lowest values …

thank you @Mladen

a.sort.take(4)
#=> [1, 2, 4, 4]
