How to print in sequence, This code is working to find the pair but how to print in sequence

#1

#include<bits/stdc++.h>
using namespace std;
#define ll long long int
int main()
{
ll n;
cin>>n;
ll ar[n];
for(ll i=0;i<n;i++)
{
cin>>ar[i];
}
ll target;
cin>>target;
map<int,int> mp;
for(ll j=0;j<n;j++)
{
ll rem=target-ar[j];
if(mp.find(rem)!=mp.end())
{
cout<<ar[j]<<" and "<<rem<<endl;
}
mp[ar[j]++];
}
}

#2

Instead of using the map try this.
Sort the given array, and then run two loops to print the sequence.
O(N^2) works because its N<=1000

#include<bits/stdc++.h> using namespace std; int main() { int n; cin>>n; int a[n]={0}; for(int i=0;i<n;i++) { cin>>a[i]; cin.get(); } int k=0; cin>>k; for(int i=0;i<n-1;i++) { for(int j=i+1;j<n;j++) { if((a[i]+a[j])==k) { cout<<a[i]<<" “<<“and”<<” "<<a[j]<<endl; } } } return 0; } this doesnt work

#5

you need to sort the array as well, it was mentioned in the approach.
