AI Writes the Missing Number Function

hi Hello! How can I help you today? Please write C++20 function to find absent number in array which contains numbers from 0 to n, but one is absent Here's an implementation of a C++20 function that can find the missing number in an array containing numbers from 0 to n, where one number is missing: #include <numeric> #include <algorithm> int findMissingNumber(const std::vector<int>& nums, int n) { int expectedSum = n * (n + 1) / 2; int actualSum = std::accumulate(nums.begin(), nums.end(), 0); return expectedSum - actualSum; } This function takes as input a vector of integers `nums` and an integer `n`, which represents the range of numbers from 0 to `n`. The function then calculates the expected sum of the numbers from 0 to `n` using the formula `n * (n + 1) / 2`. The actual sum of the numbers in the `nums` vector is calculated using the `std::accumulate` algorithm from the `<numeric>` header. Finally, the function returns the difference between the expected sum and the actual sum, which will give the missing number.

A chat screenshot shows a user asking an AI assistant to write a C++20 function that finds the missing number in an array. The assistant provides a standard arithmetic-sum solution using `std::accumulate`, making the image a humorous reaction about relying on AI to solve a basic programming task.
