hard！ 题目描述： 给出一个链表，每 k 个节点为一组进行翻转，并返回翻转后的链表。 k 是一个正整数，它的值小于或等于链表的长度。如果节点总数不是 k 的整数倍，那么将最后剩余节点保持原有顺序。 示例 : 给定这个链表：1->2->3->4->5 当 k ...
Given two integers n and k, find how many different arrays consist of numbers from 1 to n such that there are exactly k inverse pairs. We define ...
There are `N` workers. The `i`-th worker has a `quality[i]` and a minimum wage expectation `wage[i]`. Now we want to hire exactly K workers ...
