Dear Maintainer,

qqwing solver gets stuck in an infinite loop caused by casting return
value of getchar() from int to char. The comparison c == EOF is never
going to be true on systems where char is by default unsigned.

The offending line of code is:

main.cpp:491
char c = getchar();

Changing char to int solves the issue.
