Exercise: Create a method to pad an array 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)…

gistfile1.rb

class Array
  def pad!(min_size, value = nil)
    
    length = self.length
    size = min_size - length
    
    if min_size <= length
      return self
    end
    
    if min_size > length
      size.times do
    	self << value
        end
        return self
    end
  end
  
  def pad(min_size, value = nil)
  
    length = self.length
    size = min_size - length
    self_dup = self.dup
        
    if min_size <= length
      return self_dup
    end
    
    if min_size > length
       size.times do
       self_dup << value
		end
    	return self_dup
   	end
  end
