网络在线进行,比赛采取积分赛制,分为月赛和公开赛两轮。月赛举办于每年十二月、一月与二月,公开赛举办于每年的三月。
可以选择的编程语言有——C/C++、Java、Python。
【历史USACO真题举例】
After her previous artwork was met with critical acclaim Bessie was ed a iob desianina paintina sets.She desians these paintings by choosing 1<N< 10^5axis-aligned rectangles in the plane such that no two edges are collinear. The boundaries of these rectangles define the boundaries of the paintings colored regions.
Still being an avant-garde artist,Bessie decides that the painting should resemble a Holstein cow.More specifically, each region formed by the rectangles is colored either black or whiteno two adjacent regions have the same colorand the region outside of all the rectangles is colored white.
After choosing the rectangles, Bessie would like you to output one of two things based on a parameter T:
· If T=1,output the total number of regions.
·IfT=2.output the number of white regions followed by the number of black regions.
**Note: the time limit for this problem is 4stwice the default.**
INPUT FORMAT (input arrives from the terminal/stdin):
The first line contains N and T.
The next N lines each contain the description of a rectangle in the form(x1y1),(x2y2)where 1≤x1< xz≤ 2N and1≤y1<y2≤2N.(x1y1)and(x2.y2)are the bottom left and top right corners of the rectangle respectively.
It is guaranteed that all the xjform a permutation of1….2Nand the same holds for all the yi.
OUTPUT FORMAT (print output to the terminal/stdout): Asingle integer ifT=1otherwise two separated by spaces
SAMPLE INPUT
2 1
1 1 3 3
2 24 4
2022USACO竞赛复习2大要素:刷真题、“改”答案
通过练习,才能检验你对知识的掌握程度、找出问题并解决问题,也能帮助你熟悉考题脉络,适应考试节奏。
然后看编程类的答案和被别的科目不太一样,大家对答案的时候,不要只看个结果,要努力理解为什么这套解决方案是可行的。在回到自己的解题思路,试试看有没有修改的方向,说不定不想官方给的参考那样写,也能找到结局路径。
此外,刷真题还有一个好处,就是它能帮助你熟悉USACO的出题风格,复习的时候才能找对方向。当然如果觉得自己找资料有点费时,或者对比赛规则很模糊,也可点击这里预约试听【唯寻2022USACO竞赛班】——
