back to boardI think, some new tests should be added Smth like 150 1 2 3 4 .. 2 4 6 8 .. 3 6 9 12 .. 4 8 12 16 .. ............ Some solutions, which use Min Cost Flow to solve this problem can be failed (for example, my last submition). Re: I think, some new tests should be added Your test is not correct because all numbers must be from 0 to 100. But the tests in this problem are really weak. You can generate new hard tests and send them to me (sandro sobaka plotinka ru) or Vladimir Yakovlev. |
