    Pueden añadir para que los ejercicios que ya hiciste del CSES en esta parte salgan marcados, para no tener que andar entrando uno por uno para revisar si lo hiciste o mo

      Prueba este script (disculpen la mala calidad, no sé JS)

      En el primer y único comentario estan las instrucciones de como usar.

      Cualquier error comentalo alla y lo arreglo :) (aqui no para no caer en offtopic)

      Saludos

      Aquí puedes ver únicamente los problemas que aún te faltan por resolver: Lista de problemas.

      Este post solo contiene los enlaces a los problemas para facilitar la organización. No es posible añadir casillas de verificación para que los usuarios marquen su progreso(por lo menos por el momento).
