Given head which is a reference node to a singly-linked list. The value of each node in the linked list is either 0 or 1. The linked list holds the binary representation of a number. Return the decimal value of the number in the linked list. The most significant…

给你一个整数数组 nums 和一个链表的头节点 head。从链表中移除所有存在于 nums 中的节点后，返回修改后的链表的头节点。   示例 1： 输入： nums = [1,2,3], head = [1,2,3,4,5] 输出： [4,5] 解释： 移除数值为 1, 2 和 3 的节点。 示例 2： 输入： nums = [1], head = [1,2,1,2,1,2] 输出： [2,2,2] 解释： 移除数值为 1 的节点。 示例 3： 输入： nums = [5], head = [1,2,3…

You are given an array of integers nums and the head of a linked list. Return the head of the modified linked list after removing all nodes from the linked list that have a value that exists in nums.   Example 1: Input: nums = [1,2,3], head = [1,2,3,4,5]…
