Valid IPv4 Address Checker

You are given a string representing an IPv4 address. Your task is to determine whether it is a valid IPv4 address. An IPv4 address consists of four decimal numbers, each ranging from 0 to 255, separated by dots (.). Leading zeros are not allowed (except for the number 0 itself). Formally, if the IPv4 address is represented as \(a.b.c.d\), then each \(a, b, c, d\) must satisfy:

[ 0 \leq a, b, c, d \leq 255 ]

and if a part has more than one digit, it should not start with a zero. For example, 192.168.01.1 is not valid.

inputFormat

The input consists of a single line containing the IPv4 address as a string.

outputFormat

Output a single line containing either True if the IPv4 address is valid or False otherwise.
