The root of the tree has number 1. The last line contains k integers, where k is amount of leaves in the tree. These numbers describe the order in which the leaves should be visited. It is guaranteed that each leaf appears in this order exactly once. If the required route doesn't ...

Codeforces 29D Ant on the Tree 树的遍历 dfs序 题意: 给定n个节点的树 1为根 则此时叶子节点已经确定 最后一行给出叶子节点的顺序 目标: 遍历树并输出路径。要求遍历叶子节点时依照给定叶子节点的先后顺序訪问。 思路: 给每一个节点加一个优先级。 把最后一个叶子节点到父节点的路径上的点优先级改为1 把...

“I can see the tree near my home,” says the little ant. The scarab beetle puts the little ant on a leaf. “我看见我家旁边那棵树啦!”小蚂蚁说。金龟子就把小蚂蚁放在了一片树叶上。 Little Ant sees a caterpillar. “I must get home! Ca...
Many conventional methods for concepts formation in ontology learning have relied on the use of predefined templates and rules, and static resources such as WordNet. Such approaches are not scalable, difficult to port between different domains and incapable of handling knowledge fluctuations. Their resu...
The agroforests differed in the type of shade-tree composition, tree density, canopy cover, and distance to the village. On average, 43% of the species in agroforests also occurred in the lower canopy of nearby primary forest and the number of forest ant species that occurred on cacao ...
