输入一个几行几列的数组，然后用高斯算法对其进行求解-Enter a few lines and a few columns of the array, and then solve it with the Gaussian algorithm

Write a program to solve the systems of linear equations via Gauss-Seidel method, one of the iterative-method strategies produce a sequence of approximate solution vectors for the system. And compare this with the naï ve Gaussian elimination meth
