1.有三根桿子A,B,C。A桿上有若干碟子 2.每次移動一塊碟子,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)過研究發(fā)現(xiàn),漢諾塔的破解很簡單,就是按照移動規(guī)則向一個方向移動金片: 如3階漢諾塔的移動:A→C,A→B,C→B,A→C,B→A,B→C,A→C 此外,漢諾塔問題也是程序設(shè)計中的經(jīng)典遞歸問題

數(shù)字運(yùn)算,判斷一個數(shù)是否接近素數(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
