TheBeet有一片小花园,这个花园非常小,只有长宽都是1米。同时TheBeet又是出了名的懒,他从来不给这片花园里面的花浇水。当然,为了保证花的存活,TheBeet在花园中安装了几个小型自动喷灌系统,每个喷灌系统都能为其周围范围r内的花浇水。现在问题来了,TheBeet想知道他的花园中有多少地方是适合种植的——即至少有一个喷灌系统能覆盖到。-TheBeet have a small garden, the garden is very small, only the length and width are 1 m. At the same time TheBeet out of its lazy, he never gave this garden inside the flowers watered. Of course, in order to ensure the survival of flowers, TheBeet in the garden to install a few small automatic sprinkler system, each sprinkler systems are within its range r around watering the flowers. The question now to TheBeet would like to know there are many places in the garden is suitable for cultivation- that is, at least have a sprinkler system to cover.

Description 很多学校流行一种比较的习惯。老师们很喜欢询问,从某某到某某当中,分数最高的是多少。 这让很多学生很反感。 不管你喜不喜欢,现在需要你做的是,就是按照老师的要求,写一个程序,模拟老师的询问。当然,老师有时候需要更新某位同学的成绩。 Input 本题目包含多组测试,请处理到文件结束。 在每个测试的第一行,有两个正整数 N 和 M ( 0<N<=200000,0<M<5000 ),分别代表学生的数目和操作的数目。 学生ID编号分别从1编到N。 第二行包含N个整数,代表这N个学生的初始成绩,其中第i个数代表ID为i的学生的成绩。 接下来有M行。每一行有一个字符 C (只取 Q 或 U ) ,和两个正整数A,B。 当C为 Q 的时候,表示这是一条询问操作,它询问ID从A到B(包括A,B)的学生当中,成绩最高的是多少。 当C为 U 的时候,表示这是一条更新操作,要求把ID为A的学生的成绩更改为B。 Output 对于每一次询问操作,在一行里面输出最高成绩。 Sample Input 5 6 1 2 3 4 5 Q 1 5 U 3 6 Q 3 4 Q 4 5 U 2 9 Q 1 5 Sample Output 5 6 5 9 -Description Many schools have a relatively popular habit. Teachers are likely to ask, to certain of them from certain, with the highest score is. This makes a lot of students are very offensive. Whether you like it or not, you now need to do is, that in accordance with the requirements of the teacher to write a program to simulate the teacher asked. Of course, teachers sometimes need to update certain students achievements.   Input This topic contains several test cases, handle to the end of the file. In the first line of each test, there are two positive integers N and M (0 <N <= 200000,0 <M <5000), respectively represent the number of students and number of operations. Student ID numbers were compiled from one to N. The second line contains N integers, representing the N initial student achievement, the first of which is i i rep ID number of student achievement. Then there are M lines. Each line has a character C (just take the Q or U ), and two positi

In this paper, we propose a two-phase test sample representation method for face recognition. The first phase of the proposed method seeks to represent the test sample as a linear combination of all the training samples and exploits the representation ability of each training sample to determine M “nearest neighbors” for the test sample. The second phase represents the test sample as a linear combination of the determined M nearest neighbors and uses the representation result to perform classification. We propose this method with the following assumption: the test sample and its some neighbors are probably from the same class. Thus, we use the first phase to detect the training samples that are far from the test sample and assume that these samples have no effects on the ultimate classification decision. This is helpful to accurately classify the test sample. We will also show the probability explanation of the proposed method. A number of face recognition experiments show that our method performs very well.
