Why only 1 test case is passed

#1

#include

using namespace std;

int main()
{
int n,target;
int i=0;
int j=n-1;
cin>>n;
int a[n];
for(i=0; i<n; i++){
cin>>a[i];
}
cin>>target;
while(j>=i){
for( i=0; i<n; i++){
for( j=n-1; j>0;j–) {
if(a[i]+a[j]==target){
cout<<a[i]<<endl;
cout<<a[j]<<endl;
j–;
i++;
}
}
}

}

return 0;

}

hi @rathidevesh906_1dcc73a061c159bb
u have to print smaller element first followed by larger element…
refer this code–>

#include<iostream>
#include<algorithm>
using namespace std;

int main() {
	int n,s;
	cin>>n;
	int a[1000];
	for(int i=0;i<n;i++){
		cin>>a[i];
	}
	int x;
	cin>>x;
	for(int i = 0; i<=n-1; i++){
        for(int j =i+1; j <=n-1; j++){
            s = a[i]+a[j];
            if(s == x){
                cout<<min(a[i], a[j])<<" and "<<max(a[i], a[j])<<endl;
            }
        }
    }
	return 0;
}

That’s not a problem sir when I entered

[my output is->1 and 5
3 and 3] so why this happen why not it gives me ans 2 and 4

#4

you will have to run your inner loop (ie for j) till j > i and not j > 0
