19. Remove Nth Node From End of List Given a linked list, remove then-th node from the end of list and return its head. Example: Given linked list:1->2->3->4->5,and n=2.After removing the second node from the end,the linked list becomes1->2->3->5. Note: Givennwill always...
这个实现有一些问题，在很多测试用例中都不起作用。但是，在removeElement的第二个while循环中至少有一个主要问题。我尝试通过对您发送的特定测试进行最小修改来解决它。将其替换为以下代码：你
remove(int index) 和 remove(Object o) 删除元素,复杂度O(n) 源码 类说明翻译 /*** Doubly-linked list implementation of the {@codeList} and {@codeDeque} interfaces. Implements all optional list operations, and permits all elements (including {@codenull}). * 双向链表List(这里已经告诉你它的实...

3.3.1 单一元素remove() 也就是remove(int index)以及remove(Object o): public E remove(int index) { Objects.checkIndex(index, this.size); Object[] es = this.elementData; E oldValue = es[index]; this.fastRemove(es, index); return oldValue; } public boolean remove(Object o) { Object[...

4、remove(int index)方法,删除指定位置的元素 /*** Removes the element at the specified position in this list. Shifts any* subsequent elements to the left (subtracts one from their indices).* Returns the element that was removed from the list.** @param index the index of the element to ...
bool removeOne(const T &value): 移除链表中第一个与指定值相等的元素,如果成功移除则返回true,否则返回false。 int removeAll(const T &value): 移除链表中所有与指定值相等的元素,返回移除的元素个数。 void clear(): 清空链表。 查找接口: bool contains(const T &value) const: 检查链表是否包含指定值的...
add和remove的方法有些类似,这里我就不做图演示了,有两种版本,第一种是在linkedList的末尾处插入元素,另一种是在指定位置出插入元素,大家可以参考remove(index)的图来考虑第二种方法。 /*** Appends the specified element to the end of this list.** This method is equivalent to {@link #addLast}.** ...
