Write the nondestructive function insertRowCol(L, row, col, val) which takes a rectangular 2D list L and three integers and returns a new 2D list where one new row and one new column have been inserted at the locations specified by row and col. The cells in the new row and new column are all set to val, as shown below. L = [[1, 2, 3, 4], [2, 4, 6, 8], [3, 7, 2, 0]] assert (insertRowCol(L, 1, 2, 5) assert (insertRowCol(L, 3, 0, 9) == == assert (insert RowCol (L, 0, 4, 0) == [[1, 2, 5, 3, 4], [5, 5, 5, 5, 5], [2, 4, 5, 6, 8], [3, 7, 5, 2, 0]]) [[9, 1, 2, 3, 4], [9, 2, 4, 6, 8], [9, 3, 7, 2, 0], [9, 9, 9, 9, 9]]) [[0, 0, 0, 0, 0] [1, 2, 3, 4, 0], [2, 4, 6, 8, 0], [3, 7, 2, 0, 0]]) You are guaranteed that row and col will be non-negative. Also, row will be less than or equal to the number of rows of L, and col is less than or equal to the number of columns of L. Hint: How is this similar to the homework problem nondestructive RemoveRowCol? (You can write your answer on the next page for more space.)
