假设有一个棋盘(二维坐标系), 棋盘上摆放了一些石子(每个石子的坐标都为整数). 你可以remove一个石子, 当且仅当这个石子的同行或者同列还有其它石子. 输入是一个list of points. 问: 1) 给这些石子坐标, 你最多能remove多少个石子? 2) Follow-up: 若想保证remove的石子数量最大, 应按照什么顺序remove? (没有写代码) DFS count connected components: // "static void main" mus…

原标题:https://oj.leetcode.com/problems/min-stack/ Design a stack that supports push, pop, top, and retrieving the minimum element in constant time. push(x) -- Push element x onto stack. pop() -- Removes the element on top of the stack. top() -- Get the…

On a staircase, the i-th step has some non-negative cost cost[i] assigned (0 indexed). Once you pay the cost, you can either climb one or two steps. You need to find minimum cost to reach the top of the floor, and you can either start from the step w…
