#include "qutyio.h"
// Ex E3.0
//
// In this week's tutorial we used some functions from a library
// "qutyio.h" and from the <stdio.h> library to output data via
// the serial interface. This can be a useful tool for debugging
// your programme. To use the serial interface you first need to
// initialise the required hardware by calling "serial_init()";
// this only needs to be done once at the beginning of your
// programme. After this, you can use the function printf() from
// <stdio.h> to output formatted strings via the serial interface.
//
// You will need to use printf() in few different ways in this
// extension exercise:
//
// printf("foo") - prints the word 'foo' to the serial output.
// printf("bar") - prints the word 'bar' to the serial output.
// printf(" ") - prints a space to the serial output.
// printf("%02X", x) - prints the 8-bit integer 'x' to the
// serial output, formatted as two…

The cipher will use the key to determine the direction of the shift, with a ‘u’ indicating that the character must be shifted upwards while a ‘d’ indicating a downward shift. The number of characters in the key will determine the number of positions to shift. The given text variable will only contain characters from the ASCII table with values between 32 and 126. If the key is invalid (empty string, contains characters other than u and d) or the text is invalid (empty string), no encryption occurs and the function returns the original text. If the text has more characters than the key, the key will loop through again to accommodate the additional text characters. An iterative approach should be used to solve this problem.
