LabVIEW 是以数据流决定程序框图元素的执行顺序,但在某些程序框图中需要消除数据流的依赖性,这时可以考虑使用变量。LabVIEW 中的变量是程序框图中的元素,通过它可以在另一位置访问或存储数据。根据不同的变量类型,数据的实际位置也不一样。局部变量将数据存储在前面板的输入控件和显示控件中。全局变量将数据存储在特殊的通过多个VI可以访问的仓库中。不管变量将数据存储在何处,所有的变量都可以在不使用连线连接两个地方的条件下而把数据从一个地方传递到另一个地方,从而不必使用正常的数据流。

数字运算,判断一个数是否接近素数 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. Definition
