2的整数次幂FFT算法
FFT是离散傅立叶变换的快速算法,可以将一个信号变换到频域。本工程包含FFTCore.c文件,实现了FFT的蝶形同址运算,输入参数为double型的实部和虚部、logN、点数等,输出则为同址的FFT结果,分别存在double数组中,使用方便。

练习程序,问题如下:进行高精度整数的加、减、乘运算。输入两个十进制大整数M和N(M、N最长可达50位),计算运算结果并输出。【输入形式】标准输入上依次分行输入以下内容:1.第一行输入第一个大整数M。M可能带有负号,后面是最长可达50位的数字序列。2.第二行只有一个字符,可以是“+”、“-”、“*”,分别代表加、减、乘三种运算符。3. 第三行输入大整数N,格式与M相同M、N均不带有前缀的多余的0【输出形式】在标准输出上打印运算结果,输出一行字符序列,是大整数M和N和运算结果。如果该运算结果是正数,则直接输出各位数字序列;如果是负数,则首先要输出负号。各位数字紧密输出,不带有前缀的多余的0。-practice procedures, as follows : high-precision integer for the addition, subtraction, multiplication. The importation of two decimal integer big M and N (M, N up to a maximum of 50), the calculated results of operations and output. Entry forms : standard input on the importation of branches were the following : 1. The first line inputs, a large integer M. M may have negative, is back up to 50 digital sequence. 2. Only a second line of characters could be "","-","*", respectively, plus or minus, by three operators. 3. The third line inputs large integer N, M and the same format M, N are not redundant with the prefix 0 output-- in the form of print on standard out

旅行商问题
某售货员要到若干城市去推销商品,已知各城市之间的路程(或旅费)。他要选定一条从驻地出发,经过每个城市一遍,最后回到驻地的路线,使总的路程(或旅费)最小。
例如:给定4个城市{1,2,3,4}及其各城市之间的路程
最优路线是1,3,2,4,1,
其最短路程是25-a salesman, traveling salesman problem, a number of cities to sell commodities, the known distance between the city (or travel). He selected from a resident, after each city again, the last resident to return to the line, making the total distance (or travel) is the smallest. For example : given four cities (1,2,3,4) and the distance between the city optimal route is 1,3,2,4, 1, the shortest distance is 25
