Week 12: Assignment 12

1. What is the key operation performed when the number n in the Collatz Conjecture is even?

  • Add 1
  • Multiply by 3 and add 1
  • Divide by 2
  • Subtract 1

2. What happens to an odd number n in the Collatz Conjecture sequence?

  • It is divided by 2
  • It remains unchanged
  • It is replaced by n×3+1
  • It is replaced by n−1

3. What is the ultimate goal of the Collatz Conjecture sequence?

  • Reach the number 0
  • Return to the starting number
  • Reach the number 1
  • Cycle through odd numbers

4. Which of the following best describes the Collatz Conjecture?

  • It has been proven for all natural numbers
  • It remains an unsolved problem in mathematics
  • It is a trivial problem with a simple solution
  • It only applies to prime numbers

5. What is the main idea behind the PageRank algorithm used by Google?

  • Count the number of keywords on a page
  • Rank pages based on random walks on a graph of web links
  • Rank pages based on user reviews
  • Rank pages alphabetically

6. In PageRank, what happens when a page has a higher number of inbound links from other important pages?

  • Its rank decreases due to the load on the server
  • Its rank increases
  • Its rank remains unchanged
  • It is marked as a less relevant page

7. Which technique is used in the PageRank algorithm to determine the rank of a web page?

  • Depth-first search
  • Hyperlink analysis
  • Random walk simulation
  • Breadth-first search

8. PageRank relies heavily on the structure of the:

  • Web page content
  • Hyperlink network between web pages
  • User interaction data
  • Server location

9. PageRank was developed primarily to solve which problem?

  • Calculating the shortest path in a network
  • Ranking the importance of web pages on the internet
  • Counting the total number of web pages
  • Reducing the size of search engine databases

10. For which values between 200 and 3000 does the Collatz Conjecture not converge to 1?

  • 2498.0
  • 1576.0
  • 2789.0
  • None of the given options

 Week 1 Assignment Solution The cat wants to move 100 steps away slowly, and by the time it finishes moving 100 steps, it needs to slowly rotate as well towards the opposite direction. Can both these tasks be accomplished by using single loop in scratch?  Answer : YES  Which block moves the cat as described in the previous question ? Answer : [Option 3]  What does the cat say here ? Answer : [Option 4]  Says the number 4, and its multiples each for 1 second, till 40 and changes the value of number variable by adding previous value with 4. From the previous question, what is the value of number variable after the loop ends ? Answer : [Option 2]  44 Let answer for previous question be stored in variable x, what does the cat say after the execution of the loop ? Answer : [Option 3]  29  Which of the following is use case of variables in programming. Answer :  [Option 2]  They help in storing and retrieval of information/da...
