Asymptotic Analysis - How the run time of a program depends on the size of the problem Exact Analysis - Provides a more specific measure of algorithm efficiency than asymptotic analysis. Divide and Conquer Algorithm - An algorithm that solves a problem recursively by splitting it into a fixed number of smaller non-overlapping subproblems of the same type Greedy Algorithm - An algorithm that follows problem solving heuristic of making optimal choices at each stage. Disadva...

AQA A-Level computer science 03 / Fundamentals of Algorithms bubble sort - ANSWER-Compares each pair of elements in the array and swaps them if necessary. O(N^2) because it passes through the array N times. Since each pass through the array is N operations, this is N times N operations = N^2 operations in total. This is known as a polynomial time algorithm (quadratic time). It is slow and generally a bad choice for sorting. Good choice if arrays are almost sorted. it features a loop wit...

Big O Notation A way of expressing the worst-case run-time of an algorithm, useful for comparing the speed of two algorithms. Big Theta Notation A way to express the average case runtime of an algorithim, Big Omega Notation A way to express the lower bound of an algorithims run time Loop Invariant A statement that holds true for all iterations of an algorithim. Can be proved by induction Basic Operation The operation within a function that is done the most times. Used to find the time comple...

WGU C173 Scripting and Programming – Foundations Final Objective Assessment What is instantiation? Creating instances of a class What is abstraction? Focus on the essential qualities of something rather than one specific example. For example, if I say a table you have an idea of what I mean even though I didn't say if it was wood/glass or big/small. This is the essential idea behind creating classes. What is encapsulation? Surrounding something, not just to keep the contents together, but al...

Recursion correct answers A strategy for solving problems where a method calls itself Recursion relies on the runtime call stack 'every method invocation gets its own stack space Tail recursion correct answers -Single recursive call thats the last thing performed in the method 'can easily be turned into a loop Non-tail recursion correct answers -The recursive call are not performed last in the method Recursion vs. Iteration correct answers -Iterative are more efficient 'b/c i...
