Program to check whether the given number is Buzz Number or not

A number is said to be Buzz Number if it ends with 7 OR is divisible by 7.
The task is to check whether the given number is buzz number or not.

Examples:

Input : 63
Output : Buzz Number
Explanation: 63 is divisible by 7, one
of the condition is satisfied.

Input : 72
Output : Not a Buzz Number
Explanation: 72 % 7 != 0, 72 is neither 
divisible by 7 nor it ends with 7 so 
it is not a Buzz Number.

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

{ 
    // checking if the number 
    // ends with 7 and is divisible by 7 
    return (num % 10 == 7 || num % 7 == 0); 
}

Output:

Buzz Number
Not a Buzz Number

Time complexity : O(1) as there are atomic statements and no loops.
