Algorithm Efficiency Quiz

What is the most efficient way to iterate over a list in Python?

• Use a while loop

• Use a switch statement

• Use a for loop

• Use list comprehension

Which sorting algorithm has the best time complexity for large datasets?

• Bubble Sort

• Insertion Sort

• Merge Sort

• Selection Sort

In terms of algorithmic efficiency, what is the best approach to find the maximum element in an array?

• Sort the array and return the last element

• Iterate through the array once while keeping track of the maximum element found.

• Create a hash table to store elements and their frequencies

• Use a nested loop to compare each element with all others

When optimizing loops, what is the significance of loop unrolling?

Which data structure is most suitable for implementing a priority queue with efficient operations?

• Stack

• Binary heap

• Queue

• Linked list

What is the time complexity of a binary search algorithm?

• O(n^2)

• O(n)

• O(1)

• O(log n)

How can you optimize a recursive function to avoid stack overflow?

• Convert the recursive function into an iterative function by using a loop.

• Add more base cases to the recursive function

• Use a different programming language

• Increase the stack size limit

What is the purpose of memoization in dynamic programming?

• Memoization is used to increase the complexity of algorithms

• Memoization is only applicable to recursive functions

• The purpose of memoization in dynamic programming is to store and reuse the results of expensive function calls to improve efficiency.

• Memoization is a technique to reduce the number of function calls

Which loop construct is generally more efficient in terms of performance - for loop or while loop?

• while loop

• nested loop

• do-while loop

• for loop

What is the time complexity of a bubble sort algorithm?

• O(n^2)

• O(n)

• O(nlogn)

• O(1)
