SUMMING
Find the sum of $x$ smallest distinct numbers of the series $2^i \times 3^j$ ($i, j \ge 0$).
- the first number of the series is $1 = 2^0 \times 3^0$
- the second number of the series is $2 = 2^1 \times 3^0$
- the third number of the series is $3 = 2^0 \times 3^1$
- the fourth number of the series is $4 = 2^2 \times 3^0$
- the fifth number of the series is $6 = 2^1 \times 3^1$
As the sum can be huge print sum modulo $k$.
Input
The input contains 2 numbers $x$ and $k$: $1 \le x \le 10^{14}$, $1 \le k \le 10^8$
Output
The output contains sum of the first $x$ numbers of the series modulo $k$.
Example
Input: 1 1000 Output: 1 Input: 2 1000 Output: 3
Explanation: $3 = 2^0 \times 3^0 + 2^1 \times 3^0 \pmod{1000}$.
Input: 4 1000 Output: 10 Input: 6 2 Output: 0 Input: 16 1000 Output: 300
