Difficulty: Medium
About this MCQ
This Medium Algorithms question asks: Which of the following best names the concept in which an optimization technique that stores the results of expensive function calls to avoid recomputing them? The correct choice is D. Memoization. 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. Insertion sort
Why not A: “Insertion sort” does not fit this question. The answer is Memoization.
- B. Space complexity
Why not B: “Space complexity” does not fit this question. The answer is Memoization.
- C. Amortized analysis
Why not C: “Amortized analysis” does not fit this question. The answer is Memoization.
- D. Memoization ✓
Correct answer
D. Memoization
Explanation
Memoization is the term that matches “Which of the following best names the concept in which an optimization technique that stores the results of expensive function calls to avoid recomputing them” (option D). Option A (Insertion sort) does not fit this question. Option B (Space complexity) does not fit this question. Option C (Amortized analysis) does not fit this question. For this Algorithms question, the accepted answer is Memoization.
