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 n 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)
