You can buy album 1 at cost of 10 and can also buy last song at 13 to total cost = 23 and greatness is 2+2+1+2 = 7…
For the second test case,
Buy album 1 at cost 14 and you will get 2+2+1=5 greatness…
Basically there are individual prices for each song and if you buy whole set of song(album) then you may get some discount on price…
