The word `internationalization` is sometimes abbreviated to `i18n`. This comes from the fact that there are 18 letters between the first `i` and the last `n`.  You are given a string s of length at least 3 consisting of lowercase English letters. Abbreviate s in the same way.
s = input()
print(s[1] + str(len(s)) + s[len(s)-1])
s = input()
print(s[0] + str(len(s)-2) + s[len(s)-1])
