Implement Array#pad and Array#pad!. Each method accepts a minimum size (non-negative integer) and an optional pad value as arguments. If the array's length is less than the minimum size, Array#pad should return a new array padded with the pad value up to the minimum size. For example, ruby [1,2,3].pad(5) should return [1,2,3,nil,nil] And ruby [1…

pad.rb

class Array
  def pad!(min_size, value = nil)
    x = min_size - self.count
    x.times {self << value}
    self  
  end

  def pad(min_size, value = nil)
    self.clone.pad!(min_size, value)
  end
