Test case 4 not passed( arrays -target sum pairs

#1

Your code fails if there are multiple pairs with same values.
Input :
3
2 3 3
5

Expected Output :
2 and 3
2 and 3

Your Output :
2 and 3

resolved that issue that u have mentioned but still test case 4 not passing …here is my code

#4

#include using namespace std; void sumequaltarget(int a[],int target, int n){ int b[n]; for(int i=0;i<n;i++){ b[i]=a[i]; } for(int i=0;i<n;i++){ for(int j=0;j<n;j++){ if((a[i]+b[j])==target){ if(a[i]<=b[j]){ cout<<a[i]<<" and “<<b[j]<<endl; b[i]=-100; }else{ cout<<b[j]<<” and "<<a[i]<<endl; b[i]=-100; } } } } } int main() { long long int n; cin>>n; int a[n]; for(int i=0;i<n;i++){ cin>>a[i]; } int target; cin>>target; sumequaltarget(a,target,n); return 0; }

#5

@myself.yash.srivastav
Your code considers pairs of numbers with themselves as well.
Input :
3
2 3 4
6

Expected Output :
2 and 4

Your Output :
2 and 4
3 and 3
