Why we need to use function for this part? When I tried to execute the solution its give me wrong answer?!

Could I have the solution in python? + do I need to use function for this step or call a function from part one of the question?

88% 23.06 + Answer 1 of 1 + Solution: 5.2) CODE: def edge_removal(adj_matrix, i, j): #function to remove the edge (j) from the adjacency matrix adj_matrix[04) = 0 #simply setting the value of (j) in the matrix to 0 adj_matrix[i][j] = 0 #undirected graph needs (ji) to be set to 0 too, for removal of the edge for row in adj_matrix: #nested for loops to print the modified adjacency matrix for elem in row: print(elem, end="") print) Screenshot for reference: def edge_removal(adj_matrix, i, j): adj_matrix[i][j] = 0 adj_matrix()][i] = 0 for row in adj_matrix: for elem in row: print(elem, end=" ") print) 5.3) 88% 23.06 + Answer 1 of 1 D + for elem in row: print(elem, end=" ") print() 5.3) Algorithm: Step 1: For every element adj_matrix[i][j] such that i + j
