矩阵连乘积的加括号方式数
资源描述给定n个矩阵{A1，…，An}，其中Ai和Ai+1可乘，i=1,2,…,n-1。考察矩阵连乘积加括弧的方式数。
如四个矩阵连乘积A1A2A3A4，共有五种不同的加括弧方式：
( A1 ( A2 ( A3 A4 ) ) )
( A1 ( ( A2 A3 ) A4 ) )
( ( A1A2 ) ( A3 A4 ) )
( A1 ( A2 A3 ) A4 )
( ( ( A1 A2 ) A3 ) A4 )

正整数x 的约数是能整除x 的正整数。正整数x 的约数个数记为div(x)。例如，1，2，5，10 都是正整数10 的约数，且div(10)=4。设a 和b 是2 个正整数，a≤b，找出a 和b之间约数个数最多的数x。
对于给定的2 个正整数a≤b，编程计算a 和b 之间约数个数最多的数。
数据输入
输入数据由文件名为input.txt的文本文件提供。文件的第1 行有2 个正整数a和b。
结果输出
程序运行结束时，若找到的a 和b 之间约数个数最多的数是x，将div(x)输出到文件output.txt中。
输入文件示例 输出文件示例

-Positive integer x can be about a few of the positive integer x divisible. Positive integer x the approximate number recorded as the number of div (x). For example, 1,2,5,10 are about 10 positive integer number, and div (10) = 4. Set a and b are two positive integers, a ≤ b, to find a and b between about a few number of the largest number of x. For a given two positive integers a ≤ b, Programming calculated a and b between about a few number of the largest number. Data entry input data from the document text file named input.txt provide. File line 1 has two positive integers a and b. The results run the end of the output, if found between a and b of about a few number o
