How do you implement a counting sort algorithm in C++

C++

🤖 Code Explanation

int main() {
vector arr = { 10, 7, 9, 2, 8, 1, 5, 4, 6, 3 };
int n = arr.size();

countingSort(arr, n);

for (int i = 0; i < n; i++) {
cout << arr[i] << " ";
}
return 0;
}

This code sorts an array using the counting sort algorithm. The array is first scanned to find the maximum value. A count array is then created with indices from 0 to the maximum value. The array is then scanned again, and for each element in the array, the corresponding element in the count array is incremented by 1. Finally, the sorted array is printed out, with each element appearing the number of times specified by the count array.
