# Given a valid (IPv4) IP `address`, return a defanged version of that IP
# address.
# 
# A _defanged  IP address_ replaces every period `"."` with `"[.]"`.
# 
# 
# 
# **Example 1:**
# 
#     
#     
#     Input: address = "1.1.1.1"
#     Output: "1[.]1[.]1[.]1"
#     
# 
# **Example 2:**
# 
#     
#     
#     Input: address = "255.100.50.0"
#     Output: "255[.]100[.]50[.]0"
#     
# 
# 
# 
# **Constraints:**
# 
#   * The given `address` is a valid IPv4 address.
