Answer / Md Hasan Ahmad
Here is an example implementation using recursion:n```javanvoid printPermutations(String str, int l, int r) {n if (l == r) {n System.out.println(str);n return;n }n for (int i = l; i <= r; i++) {n str = swap(str, l, i);n printPermutations(str, l+1, r);n str = swap(str, l, i);n }n}nString swap(String str, int i, int j) {n char temp; temp = str.charAt(i);n str = str.substring(0, i) + str.substring(j, i) + str.substring(j+1, i+1) + str.substring(0, j);n return str;n}n```
