题目描述

Chef likes to solve difficult tasks. This time, he tried to solve the Big Famous Unsolvable $A+B=C$. One of his friends played a prank on Chef and randomly shuffled the bits in $A$ and $B$ (independently in each number). However, the funny thing is that the sum of the resulting numbers remained $C$ even after shuffling.
Chef is now wondering: in how many ways is it possible to shuffle the bits of $A$ and the bits of $B$ such that their sum after shuffling is equal to $C$? Let's denote the integers obtained by shuffling the bits of $A$ and $B$ by $A_s$ and $B_s$ respectively; two ways $(A_{s1}, B_{s1})$ and $(A_{s2}, B_{s2})$ are considered distinct if $A_{s1} \neq A_{s2}$ or $B_{s1} \neq B_{s2}$.
It is allowed to add any number (possibly zero) of leading zeroes, i.e. bits $0$, to $A$ and any number of leading zeroes to $B$ before shuffling the bits.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first and only line of each test case contains three space-separated integers $A$, $B$ and $C$.

-----Output-----
For each test case, print a single line containing one integer — the number of ways to shuffle the bits.

-----Constraints-----
- $1 \le T \le 1,000$
- $1 \le A, B, C \le 10^9$
- $A+B = C$

-----Subtasks-----
Subtask #1 (50 points): $1 \le A, B, C \le 10^5$
Subtask #2 (50 points): original constraints

-----Example Input-----
2
1 2 3
369 428 797

-----Example Output-----
2
56

-----Explanation-----
Example case 1: We can consider $A=01$ and $B=10$ in binary. Then, there are two possible ways: swapping the two bits of $A$ and the two bits of $B$ ($A_s=10$, $B_s=01$ in binary, $2$ and $1$ in decimal representation) or not shuffling any bits.
