ignore mat3. The practice must be done without using vectors.

Step 3: Matrix to array in spiral order Create an one dimensional dynamic array called TS composed by the elements of mat3 taken in spiral order. You can't do this in your main function. Example 1: 1 +2 N + 3 4 5 6 7 - 84 -9 Input: mat3 = [[1,2,3],[4,5,6], [7,8,9]] TS: (1,2,3,6,9,8,7,4,5)
