数根 数也有根吗？有！数根就是把一个数的各个数位上的值相加，直到得到一个一位数为止。请你编写一个程序来计算任意数N（0≤N≤1000000000000）的根。 输入： 输入有多个案例。每一个案例为一行，每行只有一个整数N。当输入的N是-1时，输入结束。 输出： 每一个案例输出一行。每行只有一个数字，就是N对应的数根。 Sample input 39 -1 Sample output 3-Number of root number also has roots do? There is! The number of roots is to a number of different values on the digital sum until they have been a number of up to one. Please write a program to calculate an arbitrary number N (0 ≤ N ≤ 1000000000000) roots. Input: Enter a number of cases. Each case for the line, each line is only an integer N. When the input of N is-1, the input end. Output: the output line of each case. There is only one number per line, that is, N corresponds to the number of roots. Sample input 39-1 Sample output 3

　　笔者在开发县级电网调度自动化系统的过程中，碰到一个要绘制电力系统一次接线图的问题。由于电力系统一次接线图比较复杂，图上有一 些特殊的符号，象变压器符号、开关符号等等，用一般的编程方法来绘制比较困难，因此，笔者用C语言开发了一个手工绘制电力系统一次接线图 的键盘绘图程序，使用该程序绘制的一次接线图符合用户需求，效果良好。-writer in the development of county-level SCADA process, encountered a power system to draw a diagram of the problem. The electric system diagram of a more complex map some special symbols, symbols like transformers, switch symbol, and so on, using common programming methods to map more difficult, therefore, I used the C language development of a hand-drawn power system diagram of a keyboard mapping procedures, the use of the program was produced by a diagram meet the demands of users, to good effect.
