Algo-143_ Blue Bridge Cup _ Algorithm Training _ String transformation

The problem description believes that after this semester of programming training, we have mastered the operation of the string is quite skilled. Today, Mr. Xu wants to test everyone's mastery of string manipulation. Teacher Xu himself defined the 1,2,3,4, 5 of these 5 parameters refer to different 5 kinds of string operations, you need to according to the parameters passed, according to teacher Xu's rules, the input string format conversion. Teacher Xu specified the following actions:1convert all to uppercase output, such as ABC into ABC2convert all to lowercase output, such as ABC into ABC3indicates that the string is output in reverse order, such as ABC into CBA4represents converting uppercase letters in a string to lowercase letters, and lowercase letters into uppercase output, such as ABC to ABC 5 to convert all lowercase letters, and convert all successive substrings into their corresponding abbreviated output, such as ABCD conversion to a-D, Second,-represents at least 1 letters, and if it is AB, it does not need to be converted to an abbreviated form. Input format a total of one row, respectively, refers to the corresponding operation of the number and string, the two are separated by a space, the string is all composed of the English letter output format output according to the above rules converted the corresponding string sample input5Abcdee Example output a-the EE data size and the contract input string length are up to 200.
