只要能把这样的环处理掉就行了Input: 3 3 A = 1 2 3 D D = 10 20 G G = 100 200 300 400 A A 70000000 70000032 D 70000000 70000032 G 70000000 70000032 Output: 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 1 2 3 10 20 100 200 300 400 由于zip的复杂度是log级的，所以即使有环，递归几次问题不大。 Followed by: Post your reply here: |
