Next permutation challenge

#1

I am failing one test case.Please help me find what’s wrong.

#2

no need to write the condition if(!next_permution())
because if next permutation is not possible
then it give false and change the array to intial stage which is sorted

suppose arr={3,2,1}
then after next permutation arr become {1,2,3} and function returns false;

Modified Code

if you want to ask something about this feel free to ask
i hope this helps
if yes show your response with :heart: and don’t forgot to mark doubt as resolved

#3

But i haven’t initially sorted the array. Do the next permutation function automatically sort the array on returning false?

#4

yes because after last combination
next one will be sorted itself
