}//Find the middle element for the list.ListNode mid = this.findMiddleElement(head);//The mid becomes the root of the BST.TreeNode node =newTreeNode(mid.val);//Base case when there is just one element in the linked listif(head ==mid) {returnnode; }//Recursively form balanced BSTs ...
可以看到,当fast == NULL或fast->next == NULL时(终止条件),返回的slow指针恰恰就是链表的中间节点。 struct ListNode* middleNode(struct ListNode* head){ struct ListNode* slow = head; struct ListNode* fast = head; while(fast != NULL && fast->next != NULL) { slow = slow->next; fast = ...
ListNode* middleNode(ListNode* head) { if(head==nullptr) return head; ListNode *p1=head, *p2=head;while(p2 && p2->next){p1=p1->next;p2=p2->next->next; } return p1; } };方法二、按顺序将每个结点放入数组 A 中。然后中间结点就是 A[A.Length/2],因为可以通过索引检索每个结点。 标签...
【题目】For a undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called minimum height trees (MHTs). Given such a graph, write a function to find all the...
