1.有三根桿子A,B,C。A桿上有若干碟子
2.每次移動(dòng)一塊碟子,小的只能疊在大的上面
3.把所有碟子從A桿全部移到C桿上
經(jīng)過(guò)研究發(fā)現(xiàn)，漢諾塔的破解很簡(jiǎn)單，就是按照移動(dòng)規(guī)則向一個(gè)方向移動(dòng)金片：
如3階漢諾塔的移動(dòng)：A→C,A→B,C→B,A→C,B→A,B→C,A→C
此外，漢諾塔問(wèn)題也是程序設(shè)計(jì)中的經(jīng)典遞歸問(wèn)題

數(shù)字運(yùn)算，判斷一個(gè)數(shù)是否接近素?cái)?shù)
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

The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d .
Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet.
Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1.

The XML Toolbox converts MATLAB data types (such as double, char, struct, complex, sparse, logical) of any level of nesting to XML format and vice versa.
For example,
>> project.name = MyProject
>> project.id = 1234
>> project.param.a = 3.1415
>> project.param.b = 42
becomes with str=xml_format(project, off )
"<project>
<name>MyProject</name>
<id>1234</id>
<param>
<a>3.1415</a>
<b>42</b>
</param>
</project>"
On the other hand, if an XML string XStr is given, this can be converted easily to a MATLAB data type or structure V with the command V=xml_parse(XStr).

This document provides guidelines and describes how to easily port S60 2nd Edition
C++ applications to S60 3rd Edition. The document has been written based on
experiences of porting regular S60 2nd Edition applications, such as the S60 Platform:
POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from
the example are shown in Chapter 8, “Application build changes,” and in Appendix A,
“Code example." In addition, Appendix B, "Commonly used functions that require
capabilities," and Appendix C, "Commonly used interfaces that have been changed or
removed," provide useful information on some frequently used functions and interfaces
in third-party applications.
