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

[輸入]
圖的頂點(diǎn)個(gè)數(shù)N，圖中頂點(diǎn)之間的關(guān)系及起點(diǎn)A和終點(diǎn)B

若A到B無(wú)路徑，則輸出“There is no path” 否則輸出A到B路徑上個(gè)頂點(diǎn)

圖采用鄰接矩陣的方式存儲(chǔ)。
[算法的基本思想]
采用廣度優(yōu)先搜索的方法，從頂點(diǎn)A開(kāi)始，依次訪問(wèn)與A鄰接的頂點(diǎn)VA1,VA2,...,VAK, 訪問(wèn)遍之后,若沒(méi)有訪問(wèn)B，則繼續(xù)訪問(wèn)與VA1鄰接的頂點(diǎn)VA11,VA12,...,VA1M，再訪問(wèn)與VA2鄰接頂點(diǎn)...，如此下去，直至找到B，最先到達(dá)B點(diǎn)的路徑，一定是邊數(shù)最少的路徑。實(shí)現(xiàn)時(shí)采用隊(duì)列記錄被訪問(wèn)過(guò)的頂點(diǎn)。每次訪問(wèn)與隊(duì)頭頂點(diǎn)相鄰接的頂點(diǎn)，然后將隊(duì)頭頂點(diǎn)從隊(duì)列中刪去。若隊(duì)空，則說(shuō)明到不存在通路。在訪問(wèn)頂點(diǎn)過(guò)程中，每次把當(dāng)前頂點(diǎn)的序號(hào)作為與其鄰接的未訪問(wèn)的頂點(diǎn)的前驅(qū)頂點(diǎn)記錄下來(lái)，以便輸出時(shí)回溯。

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).
