GukiZ and Binary Operations
Description
We all know that GukiZ often plays with arrays.
Now he is thinking about this problem: how many arrays a, of length n, with non-negative elements strictly less then 2l meet the following condition: 
? Here operation 
means bitwise AND (in Pascal it is equivalent to and, in C/C++/Java/Python it is equivalent to &), operation 
means bitwise OR (in Pascal it is equivalent to 
, in C/C++/Java/Python it is equivalent to |).
Because the answer can be quite large, calculate it modulo m. This time GukiZ hasn't come up with solution, and needs you to help him!
First and the only line of input contains four integers n, k, l, m (2 ≤ n ≤ 1018, 0 ≤ k ≤ 1018, 0 ≤ l ≤ 64, 1 ≤ m ≤ 109 + 7).
In the single line print the number of arrays satisfying the condition above modulo m.
Input

Note
In the first sample, satisfying arrays are {1, 1}, {3, 1}, {1, 3}.
In the second sample, only satisfying array is {1, 1}.
In the third sample, satisfying arrays are {0, 3, 3}, {1, 3, 2}, {1, 3, 3}, {2, 3, 1}, {2, 3, 3}, {3, 3, 0}, {3, 3, 1}, {3, 3, 2}, {3, 3, 3}.
