Coordinates of the bottom left corner of the first black sheet are (x3,y3)(x3,y3), and the top right — (x4,y4)(x4,y4). Coordinates of the bottom left corner of the second black sheet are (x5,y5)(x5,y5), and the top right — (x6,y6)(x6,y6). Example of three ...
C. White Sheet 题目链接:https://codeforces.com/contest/1216/problem/C 题目大意:给你两个黑色矩形和一个白色矩形的左下和右上角的坐标,问你白色矩形是否能够完全被黑色矩形覆盖 解题思路:如果白色矩形能够被黑色矩形完全覆盖,则白色矩形边上的所有
由于上面的观察我们能够推知每个位置的修改是没有后效性的,也就是修改位置的顺序没有影响,因此每次修改的位置就是相邻两张图片中不同的那些位置,直接枚举即可 时间复杂度\(\Theta(nmk)\) Code Link 2. [1763C] - Another Array Problem Rating:2000 Status:Hint + Data Evaluate:Medium 注意到如下的观察: 观...
https://codeforces.com/contest/1266/problem/F 特判一些极端如almost-1和集合中仅存两点的情况 大致分两种情况 最终集于某一点或两点 这些点分立不同子树 那么处理每个点为根不同子树的最远距离 显然的,若最远距离为d,可选取[1,d]的距离 1.一点 又可分为 A.1条长度为k,s条长度为k+1的 s+1更新ans...
