Write a program to Validate an IPv4 Address. According to Wikipedia, IPv4 addresses are canonically represented in dot-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16.254.1 . The generalized form of an IPv4 address is (0-255).(0-255).(0-255).(0-255). Here we are considering numbers only from 0 to 255 and any additional leading zeroes will be considered invalid.
Your task is to complete the function isValid which returns 1 if the ip address is valid else returns 0. The function takes a string s as its only argument .
ip = 184.108.40.206
ip = 5555..555
Explanation: 5555..555 is not a valid
ip address, as the middle two portions
Complete the function isValid() which takes the string s as an input parameter and returns 1 if this is a valid ip address otherwise returns 0.
Expected Time Complexity: O(N), N = length of string. Expected Auxiliary Space: O(1)
1<=length of string <=50
Note:The Input/Ouput format and Example given are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.
