Prove by induction that the height of a perfect binary tree is log(n+1)-1. Recall that a perfect binary tree is a binary tree in which all interior nodes have two children and all leaves have the same depth.

Answers

Answer 1

To prove that the height of a perfect binary tree is log(n+1)-1, we will use mathematical induction. First, we will show that this formula holds for a tree with only one node (n=1). In this case, the height of the tree is 0, and log(n+1)-1 equals 0, so the formula holds.



Next, we will assume that the formula holds for a perfect binary tree with k nodes, and show that it also holds for a tree with k+1 nodes. To do this, we will add one node to the tree, which must be added as a leaf node. This means that the height of the tree increases by 1. By the induction hypothesis, the height of the original tree was log(k+1)-1. Adding a leaf node does not affect the depth of any other nodes in the tree, so the height of the new tree is log(k+2)-1, which is equal to log((k+1)+1)-1. Therefore, the formula holds for a perfect binary tree with k+1 nodes.

By the principle of mathematical induction, we have shown that the formula holds for all perfect binary trees.
To prove by induction that the height of a perfect binary tree is log(n+1)-1, we need to establish two steps: base case and induction step.
Base case: For n = 1 (one node), height = log(1+1)-1 = log(2)-1 = 0, which is correct as the single node tree has height 0.
Induction step: Assume the height of a perfect binary tree with n nodes is log(n+1)-1. Now, consider a tree with 2n+1 nodes (one extra level). This new tree has double the nodes plus one additional root. The height increases by 1.
New height = log(2n+1+1)-1 = log(2(n+1))-1 = log(n+1)+log(2)-1 = (log(n+1)-1)+1.
This shows the height of a perfect binary tree with 2n+1 nodes is log(n+1)-1 +1, maintaining the relationship as we add a level, proving the statement by induction.

The weather app on Myra's phone tracks the Air Quality Index (AQI), a measure of how clean the outdoor air is. When the AQI is below 51, Myra knows the air quality is considered good. Last week, the levels in her area ranged from 40 to 48. The mean AQI for the week was about 43.9, with a mean absolute deviation of about 2.4.What can you conclude from these data and statistics? Select all that apply. the food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. hydrothermal vents are geysers on the seafloor that gush super-heated, mineral-rich water. the seawater surrounding hydrothermal vents typically contains carbon dioxide (co2), molecular hydrogen (h2), hydrogen sulfide (h2s), and methane (ch4). sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located. as part of an investigation, researchers collected specimens from an area near a deep-sea hydrothermal vent. mussels in the collection were found to be dependent on molecular hydrogen in seawater. also, the researchers discovered multiple species of bacteria living in the gills of the mussels. mussels use gills for filter-feeding and gas exchange with the surrounding seawater. on the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. on the basis of the food web, which of the following members of a deep-sea biological community is most likely to also have a symbiotic relationship with chemosynthetic organisms? question 12select one: a. blind crabs b. giant tubeworms c. zoarcid fish d. octopuses when a digitally signed document is received, the recipient's device uses the sender's ____ key to verify the digital signature. eBook Calculator Problem 16-03 (Algorithmic) The computer center at Rockbottom University has been experiencing computer downtime. Let us assume that the trials of an associated Markov process are defined as one-hour periods and that the probability of the system being in a running state or a down state is based on the state of the system in the previous period. Historical data show the following transition probabilities: From Running Down Running 0.80 0.10 Down 0.20 0.90 a. If the system is initially running, what is the probability of the system being down in the next hour of operation? If required, round your answers to two decimal places. The probability of the system is 0.20 b. What are the steady-state probabilities of the system being in the running state and in the down state? If required, round your answers to two decimal places.

Deer We have a database file with ten million pages (N = 10,000,000 pages), and we want to sort it using external merge sort. Assume that the DBMS uses quicksort for in-memory sorting. Let B denote the number of buffers. 1). Assume that the DBMS has 6 buffers (B=6). How many passes does the DBMS need to perform in order to sort the file? 2). Assuming that the DBMS has 6 buffers. What is the total 1/0 cost to sort the file? 3). Suppose the DBMS has 10 buffers. What is the largest database file (expressed in terms of N, the number of pages) that can be sorted with external merge sort using 5 passes? A company reported annual income tax expense of $250,000. during the year, income tax payable decreased from a $27,900 beginning balance to a $17,900 ending balance. how much is cash paid for income taxes during the year? can u give me an answer The order of events leading to the formation of EarthSolar systems begin as solar nebula containing heavy elements, the building blocks of planetesimals. The interior of plantesimals originate as homogeneous (uniform) mixtures of molten material. Overtime, distinct layers form within plantesimals. Differentiation of Earth's layers did not need an outside force to begin this process. Rather, Earth's layers began separating soon after the planet formed. This process is similar to oil spills in oceans. When a spill first occurs, oil and ocean water are mixed. Over time, the less dense oil will float to the surface. Similarly, in early Earth, the more dense materials sank to Earth's core, and the less dense materials moved towards the surface. Eventually, layers became distinguishable because this process in effect sorted the materials of early Earth. Characteristics of these layers provide the evidence that a large object collided with Earth late in its development. Refer to the accompanying pictures, which include some of the important events leading to the formation of Earth.
