# Við gerðum alorithma á töflu sem var fyrir framan okkur og ákváðum að skipta vandamálinu niður í 4 föll
# Við enduðum með föllin printallowed sem prentar mögulegar hreyfingar.
# getinput sem sækir input frá notanda og kallar í fallið isallowd sem athugar hvort hreyfingin sé lögleg.
# ef isallowed er True þá keyrir getinput fallið nexttile sem skilar nýrri staðsetningu notenda.

# Strengirnir hér fyrir neðan geyma löglegar hreyfingar, því við meigum ekki nota list.
