#include "my.h"

/**
 * Prints a number using the length of the string as the base and the contents
 * as the alphabet. For example, if you called my_num_base(9, "RTFM"), then
 * R = 0, T = 1, F = 2, M = 3. 9 in base 4 is 21 and so the result is printed
 * out as "FT".
 *
 * If char* is NULL or empty, print an error message and return.
 * If given unary, repeat alphabet letter the specified number of times.
