Answer:- this is not a valid postfix expression
3. Dividing an array into parts is called
Group of answer choices

Answer:- partitioning
4. The O(n2) analysis of insertion sort is a(n) _______ analysis
Group of answer choices
unknown
best-case
average-case
worst-case
Answer:- average-case worst-case
Explanation:- Insertion sort technique have average-case and
worst-case both time
complexity as O(n2). But if you have to choose only one option you
must go with average-case.

Puodace a char showing the number of moves required to solve the Towers of Hanoi puzle using t 30. What is an execution frame? What is an activation record? What is contained in it? 31. Write a recursive Java method that computes the factorial of a number 2. Linear search may require up to comparisons while binary search will only require roughly comparisons 33. Sort sorts a list of values by repetitively putting a particular value into its final, sorted,...

(5 marks; questions to Reza) In Lecture 5, Travis said you can prove QuickSort takes N(n log n) time in the best case the same way he proved any comparison-based sorting algorithm takes (n log n) time in the worst case. Give that proof. Notice it doesn't follow directly: e.g., Insertion Sort takes O(n) time in the best case. You can assume QuickSort divides each array into elements less than or equal to the pivot (including the pivot itself) and...
Let us suppose that there are n elements in the un-sorted array. Answer the following? q1: How is merge sort different from quick sort? q2: What is the split ratio in merge sort? q3: What is the worst-case/average-case/best-case running time of Merge Sort? q4: Why is the worst case running time of Merge sort O(n log n) always? q5: Why does Merge Sort use a static tree in the recursion process? (It is worth noting that the Quick Sort use...
For each of the following, give the correct answer by circling one of the two choices. TRUE or FALSE. The average-ease running time of an algorithm, over all inputs of size n, is always more than its worst-ease running time. TRUE FALSE log_b(a * c) = log_b a* log_b c. TRUE FALSE Stacks support insertions and deletions in the first-in first-out (FIFO) principle.TRUE FALSE An array of size n can support insertAtRank operation in worst-ease O(1) time.TRUE FALSE A heap...

Step One This is the Measurable interface we saw in class; you will need to provide this class; this is it in its entirety (this is literally all you have to do for this step): public interface Measurable double getMeasure(); Step Two This is the Comparable interface that is a part of the standard Java library: public interface Comparable int compareTo (Object otherObject); Finish this class to represent a PiggyBank. A PiggyBank holds quarters, dimes, nickels, and pennies. You will...
What is the role of polymorphism? Question options: Polymorphism allows a programmer to manipulate objects that share a set of tasks, even though the tasks are executed in different ways. Polymorphism allows a programmer to use a subclass object in place of a superclass object. Polymorphism allows a subclass to override a superclass method by providing a completely new implementation. Polymorphism allows a subclass to extend a superclass method by performing the superclass task plus some additional work. Assume that...
