Question

C++ / C#

What is this C++ function? What is the name of the algorithm?

void SortArr(int arr[], int n) {
    for (int startIndex = 0; startIndex < n - 1; ++startIndex) {
        int smallestIndex = startIndex;
        for (int currentIndex = startIndex + 1; currentIndex < n; ++currentIndex) {
            if (arr[currentIndex] < arr[smallestIndex]) {
                smallestIndex = currentIndex;
            }
        }
        swap(arr[startIndex], arr[smallestIndex]);
    }
}

Answer 1

Read the descriptions of the algorithms , look for the one that matches the code shown.

Answer 2
