Solves system of linear equations in field Z_p, where p is prime. In case of many solutions finds the lexicografically smallest solution (smallest x1, x2…). With -e parameter prints number of solutions up to 10^12. A complete solution to http://cecko.eu/public/lineq_2013 [cs]

This was just a homework so it needs few improvements for real use.

int ascii85encode(unsigned char *input, char *output)
{
size_t inputSize = strlen((char *)input), inputIndex = 0;
unsigned int i = 0, j = 0, chunk = 0;
