// int find(int arr[10],int len,int sum);

int find(int arr[1000], int len, int key){
sort(arr, arr+len);
int i = 0 ;
int j = len -2 ;
int k = len -1 ;

while( i < j && (arr[i]+arr[j]+arr[k])==key){
    while((arr[i] + arr[j] + arr[k]) <= key && i < j && j < k ){
        if((arr[i] + arr[j] + arr[k]) == key)
            cout <<arr[i] << ", " << arr[j] << " and " << arr[k] << endl;
        i++;
    }
    j--;
    k--;
    while((arr[i] + arr[j] + arr[k]) >= key && i < j && j < k){

            cout << arr[i] << ", " << arr[j] << " and "<< arr[k] << endl;
        j--;
        k--;
    }
}

}

int main(){
int n;
cin>>n;
int arr [10000];
for(int i=0;i<n;i++){
cin>>arr[i];
}
int key;
cin>>key;
find(arr, n, key);
}

can anyone tell me the problem

#2

while( i < j && (arr[i]+arr[j]+arr[k])==key)

This condition is the problem according to me. When the code runs for the first time, this condition is false and code exits the function directly without doing anything.

in else if statement u have j++ ;
and in else u have done k-- ;

if target >temp
we can also write k-- for every value of i and j
and in else
we can write j++ for every i and k
but when i do this
#1 test casw show me wrong ans
#2 test is correct

or can u dry run else if and else statement
