DBSCAN

POJ 字符串的插入 可以将一定长度的字符串插入之前给出的字符串之中(POJ string can be inserted into a length of string into a string before being given)

数据结构，利用霍夫曼树实现文本数据的压缩。(Huffman data compression and decompression.)

说明：  给定程序中，函数fun的功能是：将a所指3×5矩阵中第k列的元素左移到第0列，第k列以后的每列元素依次左移，原来左边的各列依次绕道右边。 例如，有以下矩阵： 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 若k结果为2，程序执行结果为： 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 请在程序的下划线处填入正确的内容并把下划线删除，使程序得出正确的结果。 注意：源文件存放在考生文件夹下的BLANK1.C中 不得增行或删行，也不得更改程序的结构！ (A given program, function fun feature is: a 3 × 5 matrix referred to in the first k elements of the left column to move Section 0, the k elements of each column after column followed by the left, the original columns in the left turn Bypass on the right. For example, the following matrix: 123,451,234,512,345 If k is 2, the program execution results: 345,123,451,234,512 in the program underscore the right content at the fill and to remove the underscore, so that the program reach the right result. Note: The source files in the folder of BLANK1.C candidates are not allowed by the line or delete line, nor change the structure of the program!)

2008软件公司面试题:排序大全：简单选择排序、冒泡排序、选择排序、shell排序、快速排序、插入排序、堆排序(从小到大)、归并排序（利用递归）(2008 software companies face questions: Sort Guinness: simple choice to sort, bubble sort, select sort, shell sort, quick sort, insert sort HEAPSORT (from small to large), Merging Sort (recursive))

冒泡优化： 如果一个序列是int n[]={1,2,3,4,5,6,7,8,9} , 用正常的冒泡排序需要排8次才行，优化之后1次就好，也就是说序列越接近于正常序列，改进之后的冒泡排序的次数就越少，这样会给一个冒泡排序算法带了很大的效率。 思想：添加一个boolean变量用来判断冒泡是否是已经排好了顺序，如果boolean的值为false，说明是已经排好了，如果boolean的值true，说明没有排好，继续排。(If a sequence is int n [] = {, 1,2,3,4,5,6,7,8,9} need to row 8 times the job after optimization times like normal bubble sort, but alsomeans that the sequence is more close to the normal sequence, improved bubble sort, the less the number, which would give a bubble sort algorithm with a great deal of efficiency. Idea: add a boolean variable used to determine the bubble whether it is already lined up the order, if the boolean is false, indicating already lined up, if the boolean value of true, did not line up, continue to row.)

最小生成树两种经典算法,kruscal和Prim算法(spanning tree)

使用全排列实现hash，看看吧相信对大家会有些帮助的(Full array hash)

各种排序算法的实现，如快速排序，冒泡排序，选择排序，堆排序，二分插入排序等(Implementation of various sorting algorithms, such as quick sort, bubble sort, selection sort, heap sort, binary insertion sort, etc.)

COM中使用SAFEARRAY数组例程，代码中给了两种数组的用法，一种是字符串数组，另一种是自定义数据结构数组。 (use COM SAFEARRAY array routines, a code for the use of two arrays, a string array, and the other is from the definition of array data structure.)
