why all the testcases are not passed
#include<bits/stdc++.h> using namespace std; int main() { int n; cin>>n; int* a=new int[n]; int j=0,sum=0; for(int i=0;i<n;i++) { cin>>a[i]; } for(int i=0;i<n;i++) { unordered_sets; while(j<n && s.find(a[j])==s.end()) { s.insert(a[j]); j++; } sum+= ((j-i) * (j-i+1))/2; s.erase(a[i]); } cout<<sum; return 0; }
