HELLO ! i have question.

having next things:

3:28
2:42
3:16
4:02

then i should somehow make a value of 10:46 of them, but i can only use one number for one time.
So no 2:42+2:42..
but this:
3:28+3:16+4:02=10:46

I dont understand algortihm for this, could anyone explain ? or how bruteforce way =\?
