Description
Imagine you have an array of size N-1 containing numbers from 1 to N with one number missing. How would you approach finding the missing number while keeping time complexity in mind?
1. Analytical Thinking : This question measures your ability to logically break down and analyze the problem to find an efficient solution.
2. Attention to Details : Precision is crucial as overlooking details could lead to an incorrect solution.
3. Problem Solving : You need to demonstrate your capability to solve programming problems and handle edge cases appropriately.
4. Efficiency : The best solution often requires finding the answer with the least time and space complexity possible.
1. Technical Competence : To assess your foundational coding skills and understanding of algorithms.
2. Problem Complexity Handling : To gauge your ability to deal with complex problems effectively.
3. Optimization Skills : To see if you can optimize code for better performance, a key skill in software development.
4. Logical Reasoning : To evaluate your logical thinking process and whether you can come up with clear, concise reasoning for your solution.
1. Think about properties of numbers : Consider using a mathematical approach such as using the sum of an arithmetic sequence to identify the missing number.
2. Explore different complexities : Show your understanding of time complexity by explaining brute force solutions versus optimal solutions.
3. Consider space complexity : Discuss not only the time complexity but also the space complexity, and strive for a space-optimized solution.
