System of Linear Equations

You are given n\cdot(m+1) coefficients a_{i,j} and b_i which form the following n linear equations: - a_{1,1}x_1 + a_{1,2}x_2 + \dots + a_{1,m}x_m = b_1 \pmod {10^9 + 7} - a_{2,1}x_1 + a_{2,2}x_2 + \dots + a_{2,m}x_m = b_2 \pmod {10^9 + 7} - \dots - a_{n,1}x_1 + a_{n,2}x_2 + \dots + a_{n,m}x_m = b_n \pmod {10^9 + 7} Your task is to find any m integers x_1, x_2, \dots, x_m that satisfy the giv
