Objective-C is a widely used programming language for developing software applications on Apple platforms such as iOS and macOS. Skilled Objective-C developers are in high demand, and one of the essential skills they need is working with Objective-C arrays. Arrays are a fundamental data structure in Objective-C that allow developers to store and manipulate collections of related values efficiently. This coding test focuses on assessing candidates' proficiency in working with Objective-C arrays. It presents a task description within the appropriate context and outlines the algorithms that need to be implemented to meet the requirements. To validate their solutions, candidates can execute their code with pre-defined inputs to check if the expected results are obtained. The test is automatically scored using a set of test cases that cover various scenarios, including more challenging corner cases. Once the test is completed, you can review the candidate's code and playback their actions to gain insights into their thought process. By administering this coding test in Objective-C, you can evaluate a candidate's ability to work with arrays and assess their problem-solving skills within the context of Objective-C development.
