My test case 0 is not passing though code is perfectly fine

#include<bits/stdc++.h>

#define ll long long

using namespace std;

ll firstOccurance(ll arr[],ll n,ll m){

ll s=0,e=n;

ll ans=-1;

while(s<=e){

ll mid=(s+e)/2;

if(arr[mid]==m){

ans=mid;

e=mid-1;

}

else if(arr[mid]>=m)

e=mid-1;

else

s=mid+1;

}

return ans;

}

ll lastOccurance(ll arr[],ll n,ll m){

ll s=0,e=n;

ll ans=-1;

while(s<=e){

ll mid=(s+e)/2;

if(arr[mid]==m){

ans=mid;

s=mid+1;

}

else if(arr[mid]>=m)

e=mid-1;

else

s=mid+1;

}

return ans;

}

int main(){

ll n,m;

cin>>n;

ll arr[n];

for(ll i=0;i<n;i++)

cin>>arr[i];

int q;

cin>>q;

while(q–){

cout<<firstOccurance(arr,n,m)<<" "<<lastOccurance(arr,n,m)<<endl;

}

return 0;

}
