순열을 재귀함수로

순열을 재귀 함수로 .. 

1,2, 3,4,5  int 배열을 갖고 재귀함수를 활용해서 순열 만들기

#include <iostream>
#include <memory.h>
 
using namespace std;
 
#define MAX_N 5

    for (int i = 0; i < size; i++) 
        cout << temp[i] << " ";
 
    cout << "\n";
 
}
void recursive(int a[], int n){
 
    //cout << "n -> [" <<n << " ]" << endl;
    //cout << "bufSize -> [" << bufSize << " ]" << endl;
 
     if (n == 3){
 
        DBGPrint(temp, n);
        return;
    }
 
    for (int i = 0; i < bufSize;  i++){

        }
    }

    bufSize = sizeof(arr) / sizeof(int);
 
    cout << bufSize << endl;
    recursive(temp, 0);
