Next_permutation

#1

What is the order in which next_permutation arranges the digits? Suppose my array is 1,2,3 …then what is the 1st permutation, then the second,…?

#2

hello @diganta_7777 you are asking about the time complexity of that?

#3

No, like the first o/p was 1 3 2, if was followed by 2 1 3, then it was 2 3 1… how is this done i.e. the ordering is done in increasing order?

#4

@diganta_7777 do you now what next_permutation does?
it gives the number which is next greater to the given number.

#5

so from 132 next greater we can form is 213 and then next greater we can form is 231.
it is like that.
