my code is showing tle in 3 cases and running fine in other cases
#include
#include
using namespace std;
int main(){
int n,sum;
cin>>n;
int a[n];
for(int i=0;i<n;i++){
cin>>a[i];
}
cin>>sum;
sort(a,a+n);
for(int i=0;i<n;i++){
int l=i+1;
int r=n-1;
while(l<r){
if(a[i]+a[l]+a[r]>sum){
r–;
}
else if(a[i]+a[l]+a[r]<sum){
r++;
}
else if((a[i]+a[l]+a[r])==sum){
cout<<a[i]<<", “<<a[l]<<” and "<<a[r]<<endl;
l++;
r–;
}
}
}
return 0;
}

Check this condition
else if(a[i]+a[l]+a[r]<sum){
r++; // Here it must be l++
}
Correct this and then check.
Also remove r-- from case else if((a[i]+a[l]+a[r])==sum)

If still there remain some issue with your code then
Save your code on ide.codingblocks.com and share its link.
