# A Python program to print all permutations using library function

for i in list(perm):
print (i)
# (1, 2, 3)
# (1, 3, 2)
# (2, 1, 3)
# (2, 3, 1)
# (3, 1, 2)
# (3, 2, 1)all permutations python
import itertools
print(list(itertools.permutations([1,2,3])))find all permutations of a string
void permute(string a, int l, int r)
{
// Base case
if (l == r)
cout<<a<<endl;
else
{
// Permutations made
for (int i = l; i <= r; i++)
{
// Swapping done
swap(a[l], a[i]);
// Recursion called
permute(a, l+1, r);
//backtrack
swap(a[l], a[i]);

}how to print all permutations of a string
void permutation(string s)
{
sort(s.begin(),s.end());
do{
cout << s << " ";
}
while(next_permutation(s.begin(),s.end()); // std::next_permutation
