Últimamente he hablado acerca del I concurso de programación de Tuenti. Un concurso de programación Online que se llevó acabo durante la semana pasada (del 13 al 20 de Junio, muy mala fecha).
Podéis ver los enunciados de todos los problemas, con ejemplos sobre la entrada y salida (aunque a veces no hay que hacerles mucho caso) en la web oficial del concurso, pero en Vidas Concurrentes lo encontramos todo en español.
Challenge #17 : The ¿? Porblem
También conocido como «Just do it.» por las palabras de su enunciado. Lo que no nos decían es que nos mandaban una imagen PNG en base64 por la entrada estándar. Si la abríamos como texto, después de muchos datos binarios podíamos leer un texto: «There is more data in this image than meets the eye«, pensemos ahora en esteganografía, por ahí iban los tiros.
