Benifits of Radix Sort

Algorithm for Radix Sort in C++

The Radix Sort is based on the idea that by sorting the dataset on the basis of each decimal place, it will be eventually completely sorted. Radix sort uses the counting sort algorithm as the subroutine....

Working of Radix Sort in C++

We will understand the working of Radix Sort in C++ using an example....

C++ Program for Radix Sort

C++ // C++ program to implement radix sort #include using namespace std;    // counting sort implementation void count_sort(int arr[], int n, int pos) {        // we declare a count array and initialize the array by     // 0     int count[10] = { 0 };        // we count the frequency of each distinct digit at     // given place for every element in the original array     for (int i = 0; i < n; i++) {         count[(arr[i] / pos) % 10]++;     }        // we perform prefix sum and update the count array     for (int i = 1; i < 10; i++) {         count[i] = count[i] + count[i - 1];     }        // we store our answer in the ans array     int ans[n];     for (int i = n - 1; i >= 0; i--) {         ans[--count[(arr[i] / pos) % 10]] = arr[i];     }        // here we copy the contents of ans array to our     // original array     for (int i = 0; i < n; i++) {         arr[i] = ans[i];     } }    // function to implement radix sort void radix_sort(int arr[], int n) {     // max_element() is a c++ stl function to find the     // maximum element from an array     int k = *max_element(arr, arr + n);        for (int pos = 1; (k / pos) > 0; pos *= 10) {         count_sort(arr, n, pos);     } }    // driver code int main() {     int arr[] = { 6, 210, 300, 600, 1, 3 };     int n = sizeof(arr) / sizeof(arr[0]);     radix_sort(arr, n);        // displaying the result     cout << "Array after performing radix sort : " << endl;     for (int i = 0; i < n; i++) {         cout << arr[i] << " ";     }     return 0; }...
