You found 4 wooden cubes. Each cube has six faces. How to display all the 365 (or 366) dates in a year, can you write function that takes the date as a string (or a null-terminated character array in C), such as "September 13" and then decide what to display on the 4 cubes? Using 0-5 as the indices of the faces in a cube, your answer could be a 4-element array, such as [-1, 2, 3, 1], meaning that first cube won't be used (indicated by a -1), the 3^rd face (remember it is 0-based) of the second cube will be used, 4^th face of the 3^rd cube will be used and 2^nd face of the 4^th cube will be used.
