my solution:
#include <bits/stdc++.h>
using namespace std;
int main() {
int t;
cin>>t;
while(t--){
int n,m;
cin>>n>>m;
int arr[m+1];
for(int i = 1;i<= m ;i++){
cin>>arr[i];
}
sort(arr+1,arr+m+1);
for(int i=1;i<=n;i=i+2){
bool condi = true;
for(int j=1;j<=m;j++){
if(i==arr[j]){
condi = false;
break;
}
}
if(condi)
cout<<i << " ";
}
cout << "\n";
for(int i=2;i<=n;i=i+2){
bool condi = true;
for(int j=1;j<=m;j++){
if(i==arr[j]){
condi = false;
break;
}
}
if(condi)
cout<<i <<" ";
}
cout << "\n";
}
return 0;
}
