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

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