You are given a positive decimal number $ x $ . Your task is to convert it to the "simple exponential notation". Let $ x=a·10^{b} $ , where $ 1

The only line contains the positive decimal number $ x $ . The length of the line will not exceed $ 10^{6} $ . Note that you are given too large number, so you can't use standard built-in data types "float", "double" and other.
