#P7112. Modulo Determinant
Modulo Determinant
Modulo Determinant
Given an (n)-order matrix (A), compute its determinant (|A|) modulo (p). The determinant is defined as ( |A| = \sum_{\sigma \in S_n} \text{sgn}(\sigma) \prod_{i=1}^{n} a_{i,\sigma(i)} ).
inputFormat
The first line contains two integers (n) and (p), where (n) is the order of matrix (A) and (p) is the modulus (a prime number). The next (n) lines each contain (n) integers representing the rows of matrix (A).
outputFormat
Output a single integer: the determinant (|A|) modulo (p).
