7 EDGE CASES NÊN KIỂM TRA TRƯỚC KHI KẾT THÚC CODING INTERVIEW

Trong Coding Interview tại Big Tech, tìm ra hướng giải đúng mới chỉ là một nửa chặng đường. Bạn còn cần đảm bảo code hoạt động chính xác với những trường hợp đầu vào đặc biệt, không chỉ với ví dụ có sẵn trong đề bài. Một lời giải có thể chạy đúng với input thông thường nhưng vẫn thất bại khi gặp mảng rỗng, dữ liệu trùng lặp hoặc giá trị nằm ở giới hạn cho phép. Vì vậy, trước khi kết thúc Coding…

Coding interviews in big tech companies require more than just finding the correct solution. Developers must also ensure their code works accurately with special input cases, not just the examples provided in the problem statement. One common mistake is assuming the input will always be normal, while edge cases like empty input, minimum input, duplicate values, boundary values, already sorted/reversed data, all same/all different values, and scenarios with no or multiple solutions can cause the code to fail.

Before concluding a coding interview, developers should dedicate time to testing these seven types of edge cases.
