#P4783. Matrix Inversion Modulo 10^9+7
Matrix Inversion Modulo 10^9+7
Matrix Inversion Modulo 10^9+7
Given an N×N matrix A with integer entries, compute its inverse matrix A-1 under modulo 10^9+7.
This means you need to find a matrix B such that:
\[ A \times B \equiv I \pmod{10^9+7} \]
It is guaranteed that the inverse exists.
inputFormat
The first line contains an integer N, the size of the matrix.
The next N lines each contain N space-separated integers, representing the rows of the matrix A. All integers are given modulo 10^9+7.
outputFormat
Output the inverse matrix of A modulo 10^9+7 in N lines. Each line should contain N space-separated integers.
