算法竞赛入门-枚举-7.2.4-下一个排列

好东西~next的用处~

#include <iostream>
#include <algorithm>
using namespace std;

int main()
{
int nums;
while(cin >> nums)
{
int arr[nums];
for(int m = 0;m < nums;m++)
cin >> arr[m];
sort(arr,arr+nums);
do
{
for(int m = 0;m < nums;m++)
cout << arr[m] << " ";
cout << endl;
}while(next_permutation(arr,arr+nums));
}
return 0;
}
