```cn#include <stdio.h>n#include <string.h>nnvoid merge(char *arr[], int l, int m, int r) {n int i, j, k;n char temp[r + 1];n for (i = l; i <= m; i++) {n arr[m][j++] = arr[i];n }n i = l;n j = 0;n for (k = l; k <= r; k++) {n if (strcmp(arr[i], arr[k]) < 0) {n arr[++i] = arr[k];n } else if (j == 0 || strcmp(arr[j - 1], arr[k]) > 0) {n arr[++j] = arr[k];n }n }n for (; j >= 1; j--) {n temp[--i] = arr[j][--j];n arr[j][j + 1] = ' ';n }n}nvoid mergeSort(char *arr[], int l, int r) {n if (l < r) {n int m = (l + r) / 2;n mergeSort(arr, l, m);n mergeSort(arr, m + 1, r);n merge(arr, l, m, r);n }n}nint main() {n char strings[10][50];n int i;n printf("Enter 10 strings:n");n for (i = 0; i < 10; i++) {n scanf("%s", strings[i]);n }n mergeSort(strings, 0, 9);n printf("Sorted and merged string: ");n for (i = 0; i < 10 - 1; i++) {n printf("%s", strings[i]);n }n printf(strings[9]);n return 0;n}n```
