(b) To give the postorder traversal of the tree. (5%)

3. Suppose that we are going to sort 10 numbers in the range [0, 999]. We use LSD radix sort with radix r = 10 and pass d = 3 to sort the numbers in an ascending order. The input list is linked, and the numbers are 179, 208, 306, 93, 859, 984, 55, 9, 271, and 33.
