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[0]+s[len(s)-2]+s[-1])
s=input()
print(s[0]+str((len(s)-2))+s[-1])
