+/**
+ * 1005. Spell It Right (20)
+ * 
+ * Given a non-negative integer N, your task is to compute the sum of all the 
+ * digits of N, and output every digit of the sum in English.
+ * 
+ * Input Specification:
+ * 
+ * Each input file contains one test case. Each case occupies one line which 
+ * contains an N (<= 10100).
+ * 
+ * Output Specification:
+ * 
+ * For each test case, output in one line the digits of the sum in English 
+ * words. There must be one space between two consecutive words, but no extra 
+ * space at the end of a line.
+ * 
+ * Sample Input:
+ * 12345
+ * Sample Output:
+ * one five
