#include
#include
using namespace std;
int main() {
int n;
cin>>n;
int arr[n];
for(int i=0;i<n;i++){
cin>>arr[i];
}
int key;
cin>>key;
sort(arr,arr+n);
for(int i=0;i<=n-3;i++){
key=key-arr[i];
int s=i+1;
int e=n-1;
while(s0){
if(arr[s]+arr[e]==key){
cout<<arr[i]<<", “<<arr[s]<<” and "<<arr[e]<<endl;
s++;
e–;
}
else if(arr[s]+arr[e]>key)
e–;
else
s++;
}
}
return 0;
}
in the test case last output is showing 2,3 and 4 instead of 2,3 and 5
please explain why
