Worked practice questions

What finite set of instructions solves a computational problem?

  1. A heuristic
  2. An algorithm
  3. A compiler
  4. An emulator
Show answer and solution

Correct answer: B. An algorithm

An algorithm is a well-defined set of instructions that terminates after a finite number of steps.

When does a computer program qualify as an algorithm?

  1. When it stops eventually
  2. If it runs indefinitely
  3. When it compiles quickly
  4. If it skips calculations
Show answer and solution

Correct answer: A. When it stops eventually

Computer programs qualify as algorithms only when they halt after completing finite operations.

Within what constraints must an effective algorithm be expressed?

  1. Zero memory allocation
  2. Infinite storage blocks
  3. Variable system clocks
  4. Finite space and time
Show answer and solution

Correct answer: D. Finite space and time

Effective algorithms must operate within finite constraints of space and execution time.
