4074. Consider this data sequence: \\\"fish bird reptile reptile bird bird bird mammal fish\\\". There is a CONSECUTIVE REPETITION of length 3 (the three consecutive birds) and a CONSECUTIVE REPETITION of length 2 (the two reptiles). There are also several SINGLETONs of length 1 (a singleton fish, a singleton bird, a singleton mammal, and another singleton fish).

Write some code that uses a loop to reads in a sequence of words, terminated by the \\\"xxxxx\\\". The code assigns to t the number of CONSECUTIVE REPETITIONS that were read. (For example, in the above data sequence that value would be 2.) Assume that t has already been declared but not initialized. Assume that there will be at least one word before the terminating \\\"xxxxx\\\".
