Analytics

The problem is straight and simple.

Given a number $$X$$ ,find how many positive $$A $$ ( $$A\gt 0)$$ exists, such that

1. $$ A$$ $$\newcommand*\xor{\mathbin{\oplus}}$$ $$X$$ =$$A$$ + $$X$$

2. $$A$$ $$\lt$$ $$X$$

**Input:**

The first line of the input will contain $$T$$ , the number of test-cases.

Next $$T$$ lines will contain integer $$X$$ .

**Output:**

For each test-case , output the answer in a separate line.

**Constraints:**

- $$1 \le T \le 10^5$$
- $$1 \le X \le 10^7$$

Explanation

**Explanation for 1st test case:**

For $$1$$ there is no such number.

**For 2nd case:**

For $$2$$ we have only one such number $$1$$ $$\newcommand*\xor{\mathbin{\oplus}}$$ $$2$$ = $$3$$

**For 3rd case:**

For number $$3$$ we have no such number .

**For 4th case:**

For number $$4$$ we have $$3$$ $$\oplus$$ $$4$$ = $$7$$ , $$2$$ $$\oplus$$ $$4$$ = $$6$$ and $$1$$ $$\oplus$$ $$4$$ = $$5$$. Hence the answer is 3.
