摘要： 描述： Given a list, rotate the list to the right by k places, where k is non-negative. For example: Given 1->2->3->4->5->nullptr and k = 2, return 4->5- 阅读全文

摘要： 描述： Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example, Given 阅读全文

摘要： 描述： Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1->1->2- 阅读全文

摘要： 描述： Given a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x. You should preserve 阅读全文

摘要： 描述： Reverse a linked list from position m to n. Do it in-place and in one-pass. For example: Given 1->2->3->4->5->nullptr, m = 2 and n = 4, return 1-> 阅读全文

摘要： 参考58沈剑大神架构师之路上的文章，谈谈Leader-Follower线程模型： 上图就是L/F多线程模型的状态变迁点，共6个关键点： （1）线程有3种状态：领导leading，处理processing，追随following （2）假设共N个线程，其中只有1个leading线程（等待任务），x个p 阅读全文

摘要： C语言中的左移和右移运算符移位后的结果老是忘记，最近在刷有关位操作的题目，正好整理下： 1. 左移运算符（<<） 左移运算符是用来将一个数的各二进制位左移若干位，移动的位数由右操作数指定（右操作数必须是非负值），其右边空出的位用0填补，高位左移溢出则舍弃该高位。 2. 右移运算符（>>） 右移运算符 阅读全文

摘要： Given a list of non-negative numbers and a target integer k, write a function to check if the array has a continuous subarray of size at least 2 that 阅读全文
