You are given an encrypted string, encrypted using a certain algorithm.Decrypt it ! The first and single line of input contains a string s, which each of it's characters is a lower case English letter. (1 ≤ |s| ≤ 105) Print the original string. ## Input The first and single line of input contains a string s, which each of it's characters is a lower case English letter. (1 ≤ |s| ≤ 105) ## Output Print the original string. [samples]

**Definitions** Let $ s \in \Sigma^* $ be the encrypted string, where $ \Sigma = \{a, b, \dots, z\} $ and $ 1 \leq |s| \leq 10^5 $. **Constraints** All characters in $ s $ are lowercase English letters. **Objective** Decrypt $ s $ to recover the original string $ s' $, where the decryption algorithm is implicitly defined but not specified.
