sir i have made the code for next permutation and it is passing the sample case. but it is not passing the test cases so please check my code and tell my mistake .
Next permutation test cases not passing
Sur why we added space in output but not in input as bith have sane format.
cout dont add space on its own ,its our responsibility to add space explicitly.
in input space is given , cin use this space to decide where previos number ends
