题目描述:

Mr. B is a famous music composer. One of his most famous work was his set of preludes. These 24 pieces span the 24 musical keys (there are musically distinct 12 scale notes, and each may use major or minor tonality). The 12 distinct scale notes are: 

Five of the notes have two alternate names, as is indicated above with equals sign. Thus, there are 17 possible names of scale notes, but only 12 musically distinct notes. When using one of these as the keynote for a musical key, we can further distinguish between major and minor tonalities. This gives 34 possible keys, of which 24 are musically distinct. In naming his preludes, Mr. B used all the keys except the following 10, which were named instead by their alternate names: 

Write a program that, given the name of a key, give an alternate name if it has one, or report the key name is unique. 

输入描述:

Each test case is described by one line having the format "note tonality", where "note" is one of the 17 names for the scale notes given above, and "tonality" is either "major" or "minor" (quotes for clarify). 

输出描述:

For each case output the required answer, following the format of the sample.

样例输入:

Ab minor
D# major
G minor

样例输出:

Case 1: G# minor
Case 2: Eb major
Case 3: UNIQUE题目大意：
　　①、每一行，给你两个字符串，判断第一个字符串是否属于表格一中有“=”符号的字符串，属于就输出与之相同的字符串，至于第二个字符串，照抄下来就行了，但是如果不属于有“=”连接的字符串，就要输出UNIQUE分析：
　　①、我们可以看出具有“=”关系的前三个字符第一个元素差1，而第二个相对固定，酱紫考虑问题就简洁很多了核心代码：　　

 if(s1[] == '#')
 {
     if(s1[] == 'G')
         printf("Ab %s\n", s2);
     else
         printg("%cb %s\n", s1[]+, s2);
 }
 else if(s1[] == 'b')
 {
     if(s1[] == 'A')
         printf("G# %s\n", s2);
     else
         printf("%c# %s\n", s1[]-, s2);
 }
 else
 {
     printf("UNIQUE\n");
 }
