Write a program to find the second smallest number in an array in ruby

class SecondSmallest
  def findSecondSmallest
    print "Enter the size of array"
    size = gets.chomp.to_i
    input_array = []
    print "Enter the elements of array"
    while size > 0 do 
      input_array.push(gets.chomp.to_i)
      size = size - 1 
    end
    second_smallest = input_array.sort[1]
    print "Entered array is: #{input_array}"
    print "\nSecond smallest element is: #{second_smallest}"
  end
end

p = SecondSmallest.new 
p.findSecondSmallest

Output:


Enter the size of array 5
Enter the elements of array 88
 44
 22
 11
 99
Entered array is: [88, 44, 22, 11, 99]
