Elements Occurring More Than n/3 Times in a Sorted Array
Company: Bytedance
Role: Software Engineer
Category: Coding & Algorithms
Difficulty: medium
Interview Round: Technical Screen
Quick Answer: This question evaluates a candidate's ability to design frequency-counting algorithms over sorted arrays, testing knowledge of majority-element patterns and their generalization to arbitrary thresholds. It probes whether a candidate can exploit array structure, such as sortedness, to move beyond a linear scan toward a more efficient approach using binary search. Such problems are common in coding interviews to assess algorithmic optimization and complexity analysis skills.
