## PBBN2 - Print Big Binary Numbers

no tags

Some answers for some problems could be huge binary numbers. In order to check the computation, one could ask you the sum of its digits. With a little base, the answer is a small number too, but not with a bigger base.

XerK would like to avoid precomputed results and wish check you've computed his huge numbers. Here's a problem that check computation of a big number N. A tutorial edition exists without language restrictions.

Let define the function CHK(N, B):
Input : N a big number in binary representation, B a power of two. Consider N as a base B number.
Output : the sum of its digits in this base.

Example :with B=2^8, 12345678 = 78 + 97*B + 188*B*B, so CHK(12345678, B) = 78 + 97 + 188

This should be easily computed with few bitwise-AND, bitshifts and additions.

### Input

The input begins with the number T of test cases in a single line.
In each of the next T lines there are four integers A, B, C, D, given in base 10.

### Output

For each test case :
* compute N = (A^B) XOR (C^D).
* print CHK(N, 2^16384) as a base 10 number.
(^ denote the power, and XOR the bitwise operator)

### Example

```Input:
2
7 3 5 4
1234 5678 9012 4444

Output:
806
1194204158794232147799<...snip...>9938532444216215551948305
```

### Explanations

For test case 1:
7^3 = 343, 5^4 = 625, 343 XOR 625 = 806, CHK(806, 2^16384) = 806.

For test case 2:
You have to output all 4933 digits of the result.

### Constraints

```1 < T <= 321
1 < A, B, C, D <= 10^4
```
