Radix Sort That Isn't Radix Sort

Could you solve this using radix sort? Sure! Here's an implementation of a radix sort algorithm in C++20 that can find the two missing numbers in an array containing numbers from 0 to n, where two numbers are missing and the numbers are unsigned integers: #include <vector> std::pair<unsigned int, unsigned int> findMissingNumbers(const std::vector<unsigned int>& nums) { std::vector<unsigned int> counts(n + 1); for (const auto num : nums) { counts[num]++; } std::pair<unsigned int, unsigned int> missingNumbers; for (unsigned int i = 0; i <= n; i++) { if (!counts[i]) { if (missingNumbers.first) { missingNumbers.first = i; } else { missingNumbers.second = i; break; } } } return missingNumbers; } This implementation has a time complexity of O(n) and a space complexity of O(n). The algorithm uses a `counts` vector to store the frequency of each number in the `nums` vector. Then, it iterates through the `counts` vector and checks if the count of each number is 0. If the count is 0, it means that the number is missing, and the missing number is added to the `missingNumbers` pair. When both missing numbers have been found, the loop is broken.

На скриншоте пользователь просит ChatGPT решить задачу с помощью radix sort, а модель отвечает реализацией через подсчёт частот в массиве. Шутка в том, что это вовсе не честная radix sort: ChatGPT уверенно выдаёт другой алгоритм, причём с ошибками в коде, сохраняя видимость технической убедительности. EN: A screenshot shows a user asking ChatGPT to solve a problem using radix sort, while the model responds with a frequency-counting array implementation. The joke is that this is not a genuine radix sort at all: ChatGPT confidently provides a different algorithm, complete with code errors, while maintaining the appearance of technical authority.
