def format_name(str)
  names = str.split(" ")
  new_names = []
  
  names.each do |name|
 	new_names << format(name)
  end
return new_names.join(" ")

def format(name)
  new_name = ""
  name.each_char.with_index do |char, idx|
    if idx == 0 
      new_name += char.upcase
    else 
   		new_name +=char.downcase

def format_name(str)
  parts = str.split(" ")
  new_parts = []
