Topic: Drivers ed 100 points and brainliest!

Answer: Ill explain it!

Explanation: Modern technology is extremely beneficial to drivers because the modern cars have sensors that detect the range of other cars, when they stop and you might not see or be ready for it, your car will slam the brakes for you, this alone saves many lives. Another is like a Tesla with autopilot. Lets say for example one day your really sleepy or dont feel good, its a stress to keep the car straight. You could turn on autopilot and it could assist you with your driving, and their system has shown to be for the most part very beneficial and responsive. I would say another would be cameras above traffic lights watching for speeders and getting their license plates. This is important because people who are being risky and causing hazards on the road will get a fat ticket and will be seeing court. They are less likely to run a red light if they see a camera watching. I hope this helps you!

maria [59]

Answer:

A.) in order traversal - 9 32 35 14 27 25 2 7 29

B.) pre-order traversal - 25 14 32 9 35 27 7 2 29

C.) post-order traversal - 9 35 32 27 14 2 29 25

Explanation:

Given - 25, 14, 7, 32, 27, 2, 29,9,35

To find - On a separate electronic page or sheet of paper:

1. List the values using in order traversal

2. List the values using pre-order traversal

3. List the values using post-order traversal

Proof -

Given values are -

25, 14, 7, 32, 27, 2, 29,9,35

1.)

In order is -

9 32 35 14 27 25 2 7 29

2.)

Pre-order is - (Root left right)

List nodes of first time visit

25 14 32 9 35 27 7 2 29

3.)

Post-order is - (Left Right Root)

List nodes of third time visit

9 35 32 27 14 2 29 25
