最接近点对问题是求二维坐标中的点对问题,该算法是为了将平面上点集S线性分割为大小大致相等的2个子集S1和S2,我们选取一垂直线l:x=m来作为分割直线。其中m为S中各点x坐标的中位数。由此将S分割为S1={p∈S|px≤m}和S2={p∈S|px>m}。从而使S1和S2分别位于直线l的左侧和右侧,且S=S1∪S2 。由于m是S中各点x坐标值的中位数,因此S1和S2中的点数大致相等。 递归地在S1和S2上解最接近点对问题,我们分别得到S1和S2中的最小距离δ1和δ2。现设δ=min(δ1,δ1)。若S的最接近点对(p,q)之间的距离d(p,q)<δ则p和q必分属于S1和S2。不妨设p∈S1,q∈S2。那么p和q距直线l的距离均小于δ。因此,我们若用P1和P2分别表示直线l的左边和右边的宽为δ的2个垂直长条,则p∈S1,q∈S2。

数字运算,判断一个数是否接近素数 A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

某幼儿园按如下方法依次给A,B,C,D,E五个小孩发糖果。将全部糖果的一半再加二分之一块糖果发给第一个小孩;将剩下糖果的三分之一再加三分之一块糖果发给第二个小孩;将剩下糖果的四分之一再加四分之一块糖果发给第三个小孩;将剩下糖果的五分之一再加五分之一块糖果发给第四个小孩;将最后剩下的11块糖果发给第五个小孩。每个小孩得到的糖果数均为整数。试确定原来共有多少块糖果?每个小孩各得到多少块糖果? 要求结果的输出格式为 sum=糖果总数 xa=A得到的糖果数 xb=B得到的糖果数 xc=C得到的糖果数 xd=D得到的糖果数 xe=E得到的糖果数

暂时只支持jpeg2000支持的 cdf97 和spline53 可以这样来测试: x=imread( E:\study\jpeg2000\images\lena.tif ) % see the decomposition coefficients y=wavelift(x, 1, spl53 ) using spline 5/3 wavelet figure subplot(1,2,1) imshow(x) subplot(1,2,2) imshow(mat2gray(y)) % see the reconstruction precision yy=wavelift(x, 5) using cdf 9/7 wavelet ix=wavelift(yy,-5) inverse sum(sum((double(x)-ix).^2))
