The reason why IMPOSSIBLE is not provided is because you can always provide an A[] such that no matter what B[] you get back, it is always possible to divide A+B into two subset with equal sum. So you will never run into IMPOSSIBLE case.
The judge however, will never guarantee that A + B can be divided into two subset with equal sum. If it is impossible to do that, the judge just mark your solution is Wrong Answer :) 在2022年4月21日星期四 UTC-7 17:11:16<[email protected]> 写道： > Thanks, all.
