U nizu brojeva 1 - 20 potrebno je izdvojiti sve kombinacije od 5 brojeva, bez ponavljanja, koje ispunjavaju uslov da raspon izmedju najveceg i najmanjeg broja u kombinaciji bude 10.

dobro, ko ceka taj doceka

edit: mislim da ih ima 840, nisam siguran

edit 2: da bi razlika bila 10 imamo sledece brojeve:
1 11
2 12
3 13
.
.
.
9 19
10 20

to je 10 slucajeva. u svakom slucaju izmedju ova dva broja treba da stavimo jos tri broja (da ih ima 5, i da budu ne manju od najmanjeg i ne veci od najveceg)
ima 9*8*7/3*2*1=84 kombinacija za svaki slucaj
dakle konacno resenje je 10*84=840 kombinacija
