Answer 1

You can find a simple alternative with your new requirements:

function CountWordLength (String)
  local Results  = { }
  local Continue = true
  local Position = 1
  local SpacePosition
  
  while Continue do
    SpacePosition = string.find(String, " ", Position)
    if SpacePosition then
      Results[#Results + 1] = SpacePosition - Position
      Position = SpacePosition + 1
      -- if needed to print the string
      -- local SubString = String:sub(Position, SpacePosition)
      -- print(SubString)
    else
      Continue = false
    end    
  end

  Results[#Results + 1] = #String - Position + 1
  
  return Results  
end

Results = CountWordLength('I am a boy')

for Index, Value in ipairs(Results) do
  print(Value)
end

Which gives the following results:
