Code

# Robotti on rakennuksessa, jossa on n vierekkäistä huonetta.
# Jokaisen kahden vierekkäisen huoneen välissä on ovi. Joissakin huoneissa on kolikko.
# Robotti siirtyy aina lähimpään huoneeseen, jossa on kolikko, ja poimii kolikon.
# Robotti pysähtyy, kun kaikki kolikot on kerätty tai lähin huone ei ole yksiselitteinen.
# Jälkimmäisessä tapauksessa robotti ei tiedä, miten sen tulisi toimia.
# Montako askelta robotti liikkuu yhteensä ja montako kolikkoa se kerää?
# Syöte
# Syötteen ensimmäisellä rivillä on kokonaisluku n: huoneiden määrä.
# Seuraavalla rivillä on merkkijono, jossa on n merkkiä.
# Merkkijono kuvaa rakennuksen: . on tyhjä huone, * on kolikkohuone
# ja R on robotin aloitushuone.
# Merkki R esiintyy tarkalleen kerran.
# Tuloste
# Tulosta kaksi kokonaislukua: robotin askelten määrä ja kerättyjen kolikoiden määrä.
# Esimerkki
# Syöte:
# 20
# **.*......*.R*...*..

# Tuloste:
# 4 2

# Selitys: Robotti liikkuu ensin askeleen oikealle ja kerää kolikon.
# Sitten se liikkuu kolme askelta vasemmalle ja kerää kolikon.
# Tämän jälkeen vasen ja oikea kolikko ovat yhtä kaukana ja robotti pysähtyy.
# Kuvassa on esitetty robotin sijainti eri vaiheissa.
