# Getting WA on CF

Mysolution: Solution

Error on input case:
3
1 2
2 2 3
Output

I become the guy.

Oh, my keyboard!

I think the Tester solution is wrong here. As my output is correct.

``````    #include <bits/stdc++.h>
using namespace std;
typedef long long int ll;
#define fast ios_base::sync_with_stdio(false); cin.tie(NULL); cout.tie(NULL);

int main()
{
fast
int t;
cin>>t;
int arr[t+1];
for(int i=0;i<=t;i++){
arr[i]=0;
}
int x;
while(cin>>x){
arr[x]++;
}
// for(int i=1;i<t;i++){
//     cout<<arr[i];
// }
bool res=true;
for (int i = 1;i<=t; i++)
{
if(arr[i]==0){
cout<<"Oh, my keyboard!"<<endl;
res=false;
break;
}
}
if(res){
cout<<"I become the guy."<<endl;
}
// while(t--)
// {

// }
return 0;
}
``````

implement using set in c++. see below My Code in C++;

``````#include<bits/stdc++.h>
#define fast ios_base::sync_with_stdio(false);cin.tie(0);
#define lli long long int
#define vi vector<lli>
#define pb push_back
#include<string>
#define mp map<string,lli>
#define test lli t;cin>>t;while(t--)
using namespace std;
int main()
{
lli n,p,q;
cin>>n;
cin>>p;
vi arr(p);
for(auto &it:arr)
cin>>it;
cin>>q;
vi brr(q);
for(auto &it1:brr)
cin>>it1;
set<lli>a(arr.begin(),arr.end());
for(lli i=0;i<q;i++)
a.insert(brr[i]);
if(a.size()==n)
cout<<"I become the guy.\n";
else
cout<<"Oh, my keyboard!\n";
}

I think the issue on your code is with the `while(cin>>x)` part.
You do not have to increment arr[x] every time. The input format clearly says the first number in the second line represents the number of numbers following.
Change suggested:

``````    while(x--){
int z;cin>>z;
arr[z]++;
}

int y;cin>>y;
while(y--){
int z;cin>>z;
arr[z]++;
}
``````

Link to submission after making this change:

Hope I helped!

thank you, I got it.

I see that you post both the question link and the submission link and even describe your issue in your topics. Like in this topic too. Great to see such a responsible forum member!
I see that you even tried to format your code for ease of all, but it didn’t work out.

It’s because you have to use back ticks ``` instead of `'''`. You can see how to format your code here!

@manvi_03 Yeah!,Even I was confused why the code formatting isn’t working. Thank you for mentioning the error.
