| ( 195 ) | G | Simons and Diophantus Equation | PROGRAMMING | bitmasks brute force data structures number theory |
Simons has given you two integers (n) and (m). Count the number of ordered tuples ((i, j, k)), such that: (0\le i, j, k\le m), and There exist two integers (x) and (y), such that ((i \oplus j) \cdot x + (j \oplus k) \cdot y = n), where (\oplus) denotes the bitwise XOR operation . Each test contains multiple test cases. The first line contains the number of test cases (t) ((1 \le t \le 10^4)). The description of the test cases follows. The only line contains two integers (n) and (m) ((1\le n\le 10^9), (1\le m\le 3\cdot 10^5)) — the given integers. It is guaranteed that the sum of (m) over all test cases does not exceed (3\cdot10^5). For each test case, output a single integer — the number of ordered tuples ((i,j,k)) that satisfy the condition. In the first test case, there are (18) tuples that satisfy the conditions. For example: ((2,1,2)) is a valid tuple because the equation ((2\oplus 1)\cdot x+(1\oplus 2)\cdot y=3) has an integer solution (x=3), (y=-2). ((1,1,0)) is also a valid tuple because the equation ((1\oplus 1)\cdot x+(1\oplus 0)\cdot y=3) has an integer solution (x=100), (y=3). ((2,0,2)) is not a valid tuple because the equation ((2\oplus 0)\cdot x+(0\oplus 2)\cdot y=3) has no integer solution. ((1,1,1)) is not a valid tuple because the equation ((1\oplus 1)\cdot x+(1\oplus 1)\cdot y=3) has no integer solution. ((3,2,1)) is not a valid tuple because (3 \gt 2). |
