Given an integer, check whether it is Bleak or not.

A number ‘n’ is called Bleak if it cannot be represented as sum of a positive number x and set bit count in x, i.e., x + countSetBits(x) is not equal to n for any non-negative number x.

**Example 1:**

**Input: **4
**Output: **1
**Explanation: **There is no any possible x
such that x + countSetbit(x) = 4

**Example 2:**

**Input:** 3
**Output: **0
**Explanation:** 3 is not a Bleak number as
2 + countSetBit(2) = 3.

**Your Task:**

You don't need to read or print anything. Your task is to complete the function **is_bleak()** which takes n as input parameter and returns 1 if n is not a Bleak number otherwise returns 0.

**Expected Time Complexity: **O(log(n) * log(n))

**Expected Space Complexity: **O(1)

**Constraints:**

1 <= n <= 10^{4}
