This might get you OK marks on the "problem solving" portion of a coding interview. But a programming interview will also look for signals of other skills -- did you communicate your approach? Really good candidates will verbally communicate their solution before writing code. The best often write out how a particular data structure changes with some iteration.

If you're a senior engineer, a coding interview should include some demonstration of correctness. Maybe you write one primitive test harness for a positive test case and add comments or empty methods enumerating a few other test cases.
