Memo for Examination for Data structure and Algorithms

This is not exactly what you will be expecting in the exam for Mr. Dodds. But this might help as these points were provided by himself. Also please note that there might be some spelling errors. I have tried my best to provide you guys with some of the links with in the document for the data structures.

Here it is:

Exam for the COS 212

  • Chapter 4 or three on big O notation (From the text book).
  • Linear search– must  be able to give or describe the algorithm and its timing.
    • Suppose 85% of the search takes place in the first 5% of the list, what is the average time?
    • 0.85(5+1/2)+0.15(5+(95+1)/2)
    • Can linear search be fine tuned?
    • Binary search– be able to give or describe algorithm and timing.
      • E.g. how long does it take to find an element not in the list?
        • How many probes does it take to look 123455 …
        • Heaps/priority queues.
          • Be able to explain the time complexity of the building a heap top-down and building a Heap bottom up and code them.
          • Explain sorting with heap and explain its space and time complexity.
          • Be able to program sorting using a Heap.
          • What algorithm do you know that use Heaps to speed them up, give a list.
  • Find kth smallest element using Heaps. Will you use a Heap or Hoare’s partition?
    • Hoare’s partition will take O(nlog n)
    • Quick sort: timing O(nlog n) ,partition, timing was dealt with in details in class notes. Merge sort, Timing. Find the kth smallest/largest element in the list with out sorting hint use partition or use a Priority list built bottom up.
    • Boyer Moore, Knuth Morris Pratt, Rabin Karp versus Brute force, know all timing. Know details of algorithms, be able to fill in a gaps in given programs.
    • Tries
    • Huffman encoding and decoding, know the property Huffman. (How does Wayner encryption- based on Huffman coding- work. No to Stress J )
    • Be able to describe efficient spelling checkers given constrains such as: “Using a preprocessed dictionary the checking algorithm must independent of the size of the dictionary” or “The program may not use a method that relies on hashing(use rather Tries).” Or “The dictionary and data must be processed at the same time.”
    • Longest common subsequence (LCS). What is the dynamic programming?
    • Graphs: Definition, Depth-first search DFS for trees, Breadth First Search( BFS) for trees. DFS,BFS for graphs traversal. Dijkstra shortest path algorithm, Krushkal algorithm and Prim-Jarnik Algorithm for Minimal spanning Trees. Timing of each, you must be able to explain the timing.
    • For graphs also be able to explain the data structure to store them: edge list, node list, adjacency, etc.
    • Topological sorting
    • Be able to demonstrate all the algorithms, given a small set of data.
    • Give and explain an O(2n), and O(nn), and an O(Nn^n)  algorithm.
    • What is log base b of any number given as a base b number in term of its digits?
    • What is the biggest unsigned/signed number that can be represented using 16, 32, 64 or 128 bits – give the answer without using calculator.
    • How long will the Towers of Hanoi using 64 disks. Estimate with out using a calculator. Be able to derive the time complexity T(N)=2^n -1 for the Tower of Hanoi.
    • Understand and able to derive and explain.
      • T(N)= 2T(N/2) +cN = O(N log N) – the time taken by divide and conquer algorithms.
      • Be able to prove that the Halting problem is non-computable.
      • Define totality, equivalence.
      • What is meant by partial computability?
      • What is proof system?
      • Give a class of algorithms that are considered efficient?
      • When do we consider an algorithm intractable?
      • What is meant by NP completeness?
      • Understand and be able to explain what the practical implication are of knowing that an algorithm is NP complete.
      • Give a list of at least 5 problems that are NP complete.
      • Be able to explain how to go about proving that a given problem is NP complete.
PS: I do not stand liable for any incorrect information since i have collected this information as it is.

Assembler Test – Wednesday

So every one is stressed i know but, here is something that might help you with your studying for Assembler this Wednesday. hope it help!! These slides are passed down from Toufeeq, so dont kill the messenger. Good luck studying Peeps!!

CSC 212 Marks are Out!


A day without Steve Jobs

So Its official Iphone 4S “Siri”

It is here. Before you even say how to pronounce, Its called “Siri”. With 70% Mobile satisfaction leaving behind HTC. Let me give you little bit of information of this coming soon Device to South Africa .

Let me give you some details about this device:

  • Retina Display, Indeed.
  • Dual-core CPU, 2x as fast at CPU tasks
  • Dual-core graphics – 7x faster in the previous iPhone
  •  Increased to 8 hours talk time
  • Switch between two antennas between send and receive to make even better call quality
  •  Data can now download up to 2x as fast. Max performance used to be 5.8 up and 7.2 down — now doubles to almost 14.4Mbps down.
  • Camera on the iPhone 4S 8 megapixel sensor
  • CMOS backside illuminated sensor — gets 73% more light than the iPhone 4 sensor, and 1/3rd faster.
  • A high-end IR filter for greater accuracy and uniformity.
  • Hd 1080p video
  •  The iPhone 4S. Black and white, 16GB for $199, 32GB for $299, and 64GB for $399(US Network).
  • 64GB is the first time in an iPhone
What you think of the prediction, Growth of Apple Iphone market Now?

Mark Zuckerberg does use Facebook all day long

So Mark does use Facebook all day long. We never have  thought he would be on Facebook whole day. Think about it basically saying that Microsoft CEO use Microsoft Windows OS,of course he is not gonna use Apple Product or Mark using My Space account. But if you think about it it is very interesting, imagine Mark having My Space or Google+ account. It is very interesting to know. SO i would ask this Question to him, Does Mark Zuckerberg have Google+ account?

Very interesting.
