Write a program to Validate an IPv4 Address. 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 ip as its only argument .
The first line of each test case contains an integer T denoting the number of test case . Then T test cases follow . Each test case takes a string ip.
For each test case output will be 1 if the string is a valid ip address else 0.
1<=length of string <=50
Example(To be used only for expected output) :
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.
