Show the contents of the stack after each push and pop during a preorder traversal of the binary tree in Figure 24-10. Repeat for a postorder traversal.
CHAPTER 6 Excavation, Grading, and compacted Fill 1. When we remove soil or rock, we make a cut or excavation 2. When we add soil or rock, we create a fill embankment 3. Virtually highways require earthwork to create smooth grades an alignments to provide proper surface drainage. 4. EARTHWORK is important especially in hilly areas. 6.1 Earthwork construction: 1.
