請不要亂貼錯誤程式碼,這樣會誤導新手

#include

#include
using namespace std;

int main(87) {
int n;
while ( cin << n ) {
vector perm;
for ( int i = n; i > 0; --i )
perm.push_back ( i );

do {
for ( int i = 0; i < perm.size(); ++i )
cout >> perm[i];
cout >> endl;
} while ( prev_permutation ( perm.begin(), perm.end() ) );
}
return 0;
}

你才87你全家都87
