Known issue

• The issue isn’t been solved so please make sure the width of your terminal is bigger than 110 spaces.
  
  Since every time you input a char, render() is called.
  It would using 110 spaces to overwrite what ever is rendered last time --110 is close to maximum possible input length. However, if your terminal’s width is less than 110 spaces, every time when render() is called, the result would look like a \n is output.
