Given A linked list, remove the nth node from the end of the list and return its head.For example, n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5.Solution:1 /**2 * Definition for singly-linked list.3 *

In c, when assigning values between variables of the same type, it is direct memory copying, copying their memory, and two struct variables of the same type belong to the same variable, so the assignment is copied directly according to their memory
