# 
# Given a palindromic string `palindrome`, replace **exactly one** character by
# any lowercase English letter so that the string becomes the lexicographically
# smallest possible string that **isn 't** a palindrome.
# 
# After doing so, return the final string.  If there is no way to do so, return
# the empty string.
# 
# 
# 
# **Example 1:**
# 
#     
#     
#     Input: palindrome = "abccba"
#     Output: "aaccba"
#     
# 
# **Example 2:**
# 
#     
#     
#     Input: palindrome = "a"
#     Output: ""
#     
# 
# 
# 
# **Constraints:**
# 
#   * `1 <= palindrome.length <= 1000`
#   * `palindrome` consists of only lowercase English letters.
