數字運算，判斷一個數是否接近素數 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

源代碼\用動態規劃算法計算序列關系個數 用關系"<"和"="將3個數a，b，c依次序排列時，有13種不同的序列關系： a=b=c,a=b<c,a<b=v,a<b<c,a<c<b a=c<b,b<a=c,b<a<c,b<c<a,b=c<a c<a=b,c<a<b,c<b<a 若要將n個數依序列，設計一個動態規劃算法，計算出有多少種不同的序列關系， 要求算法只占用O(n),只耗時O(n*n).

c語言版的多項式曲線擬合。 用最小二乘法進行曲線擬合. 用p－1 次多項式進行擬合，p<= 10 x,y 的第0個域x[0],y[0],沒有用，有效數據從x[1],y[1] 開始 nNodeNum,有效數據節點的個數。 b,為輸出的多項式系數，b[i] 為b[i-1]次項。b[0],沒有用。 b,有10個元素ok。

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

這個連接池是直接從JIVE中取出來的，進行了一下修改，使得連接參數直接在程序中設定而不是從屬性文件中讀取。 [b]用法：[/b] 先設定自己的連接參數，在DbConnectionDefaultPool.java文件的loadProperties方法中。注意你也需要設定連接池的log文件的存放位置。
