Deduce row order from logic clues
Company: MathWorks
Role: Software Engineer
Category: Statistics & Math
Difficulty: easy
Interview Round: Take-home Project
Four coworkers—A, B, C, and D—are standing in a single row facing north. The following clues hold:
(
1) A is somewhere to the left of C.
(
2) B is not at either end.
(
3) D stands next to exactly one of A or C.
(
4) There is exactly one person between A and B. Determine the exact order from left to right and explain your deduction steps.
Quick Answer: This question evaluates logical deduction, constraint satisfaction, and basic combinatorial reasoning used to infer ordering from positional clues. Commonly asked to assess a candidate's ability to apply discrete math and spatial reasoning within the Statistics & Math domain, it targets conceptual understanding of constraints rather than practical implementation.
