Select the accurate description of Space complexity.
Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: Select the accurate description of Space complexity. The correct choice is B. A measure of the amount of memory an algorithm uses as a function of input size.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Algorithms items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Algorithms so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Algorithms item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex.
Why not A: “An ordering of vertices in a directed acyclic graph such that for every edge, the source vertex comes before the destination vertex.” does not fit this question. The answer is A measure of the amount of memory an algorithm uses as a function of input size..
- B. A measure of the amount of memory an algorithm uses as a function of input size. ✓
- C. An algorithm that uses a degree of randomness as part of its logic to achieve good average-case performance.
Why not C: “An algorithm that uses a degree of randomness as part of its logic to achieve good average-case performance.” does not fit this question. The answer is A measure of the amount of memory an algorithm uses as a function of input size..
- D. A greedy algorithm that finds a minimum spanning tree for a connected, weighted graph by adding edges in increasing order of weight.
Why not D: “A greedy algorithm that finds a minimum spanning tree for a connected, weighted graph by adding edges in increasing order of weight.” does not fit this question. The answer is A measure of the amount of memory an algorithm uses as a function of input size..
Correct answer
B. A measure of the amount of memory an algorithm uses as a function of input size.
Explanation
A measure of the amount of memory an algorithm uses as a function of input size option B is the accepted answer to Select the accurate description of Space complexity Option A An ordering of vertices in a directed acyclic graph such that for every edge the source vertex comes before the destination vertex does not fit this question Option C An algorithm that uses a degree of randomness as part of its logic to achieve good average-case performance does not fit this question Option D A greedy algorithm that finds a minimum spanning tree for a connected weighted graph by adding edges in increasing order of weight does not.
