Error

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)

**Constraints:**

1<= n <=10^{9}
