Next permutation

#1

#include
#include
using namespace std;
int main() {
int t;
cin>>t;
for(int i=0;i<t;i++){
int n;
cin>>n;
int a[1005];
for(int i=0;i<n;i++){
int m;
cin>>m;
a[i]=m;
}
cout<<next_permutation(a,a+n);
}
return 0;

hello tishya,
After calling next_permutation .
u need to print ur array . but u r printing value return by next_permutation.

#3

#include
#include
using namespace std;
int main() {
int t;
cin>>t;
for(int i=0;i<t;i++){
int n;
cin>>n;
int a[1005];
for(int i=0;i<n;i++){
int m;
cin>>m;
a[i]=m;
}

 next_permutation(a,a+n);
 for(int i=0;i<n;i++){
 	cout<<a[i];
 }

}
return 0;
}
it is still wrong

make these changes because
a) there should be space between two elements of ur array in output
b) output of each test case should be in different line.
