Please provide the solution for the below question using python3 and show answer

3. (20 points) (Computer problem) Write a computer program that solves a linear system with a tri-diagonal matrix. 0 1 b1 0 0 C1 02 b2 0 C2 03 63 : an-1 bn-1 Cn-2 0 Cn-1 an Use the Gaussian elimination that follows the band structure. Test your code on the 100 x 100 matrix, 2 -1 0 I 1 1 0 1 X2 A= -1 2 -1 X 100 Show the first 5 entries of the solution vector. 3.
