Basic Accuracy: 55.29% Submissions: 199 Points: 1

My friend generated a series 1 4 8 9 12 17 25 28 .... . Each element of this series is known as "Dory". Your task is to find out whether a number is Dory or not.
NOTE: If n is "Dory", then return 1 else return 0.

Example 1:

Input: n = 4
Output: 1 
Explanation: 4 is Dory because 
its present in the series.

Example 2:

Input: n = 7
Output: 0
Explanation: 7 is not Dory because
its not present in the series.

Your Task:  
You dont need to read input or print anything. Complete the function nisDoryOrNot() which takes n as input parameter and returns 1 If n is "Dory" else return 0.

Expected Time Complexity: O(1)
Expected Auxiliary Space: O(1)

1<= n <=109
