A0001. Cool lines P56059
A line of words is cool if its first word, word in the middle and last word are identical.
Your task is to write a program that reads various lines, and prints if all the lines are cool, if there is not any cool line, or if there are some lines that are cool and some that are not.
Input

Output
The program has to print “all cool”, “none cool” or “both types” depending on the case.
