Delete Node in a Linked List

Problem: Delete Node in a Linked List

Since we can't delete the target node directly since we don't know the previous node, we can remove the next node of target.

Code in Python:

# Definition for singly-linked list.
# class ListNode(object):
#     def __init__(self, x):
#         self.val = x
#         self.next = None

class Solution(object):
    def deleteNode(self, node):
        """
        :type node: ListNode
        :rtype: void Do not return anything, modify node in-place instead.
        """
        node.val = node.next.val
        node.next = node.next.next
