Delete the next (n = 3) nodes (3 -> 4 -> 5) show in read nodes. Continue with the same procedure until reaching the tail of the Linked List. Head of linked list after removing nodes is returned. Example 2: Input: head = [1,2,3,4,5,6,7,8,9,10,11], m = 1, n = 3 ...
Explanation: Keep the first (m = 2) nodes starting from the head of the linked List (1 ->2) show in black nodes. Delete the next (n = 3) nodes (3 -> 4 -> 5) show in read nodes. Continue with the same procedure until reaching the tail of the Linked List. Head of linked li...
A tree rooted at node 0 is given as follows: The number of nodes isnodes; The value of thei-th node isvalue[i]; The parent of thei-th node isparent[i]. Remove every subtree whose sum of values of nodes is zero. After doing so, return the number of nodes remaining in the tree....

【leetcode】1110. Delete Nodes And Return Forest 题目如下: Given therootof a binary tree, each node in the tree has a distinct value. After deleting all nodes with a value into_delete, we are left with a forest (a disjoint union of trees)....
After deleting all nodes with a value into_delete, we are left with a forest (a disjoint union of trees). Return the roots of the trees in the remaining forest. You may return the result in any order. Example 1: Input: root = [1,2,3,4,5,6,7], to_delete = [3,5] ...
