if a,b and c are numbers

if(a>b) { if(a>c) {("a is largest")} else {("c is largest")} } else { if(b>c) {("b is largest")} else {("c is largest")} }

simply put all numbers in array and call max method.

a=[2,3,4] a.max

data = [10, 20, 70, 60, 40, 30] ordered_data = data.sort_by {|num| -num}

p ordered_data p ordered_data[0..2]

--output:-- [70, 60, 40, 30, 20, 10] [70, 60, 40]

data = [10, 20, 70, 60, 40, 30] ordered_data = data.sort_by {|num| -num}

p ordered_data p ordered_data[0..2]

Or data.sort.last(3)

I think you might need ruby 1.9 to be able to pass an argument to last like that.
