instead of cout << sum[i] do cout << vect[i].first

For storing the count of the fruits I made array hash[m+1]. In this array: 'iāth index contain sum of all the prices of type āiā.

You guys need to understand that when you are asking for help.

Please give submission link instead of just copy pasting code here. Even if it is properly formatted, I feel long codes spam the whole post and the chances of your doubt getting resolved becomes even lesser.

And posting your code multiple times is spamming the post even more. Edit your previous comment in case you want to edit something. Donāt just post it again and again.

Itās not mandatory but explaining what you are doing in you code will catch even more attention of people and your doubt will be resolved sooner.

I think @vijju123 (the moderator) would agree.

Isnāt mapping a better option?? If not then why??

Yes, it is

But for First Question we shouldnāt bother getting into map and iteratorās stuff .

It gets actually quite simple if you use maps because you donāt need to take care about used or not used flags.

Iāve done it with map only, you could have a look if you want

Yay!! I also solved using map and the solution seems quite easyā¦ Thanks Btw

whatās wrong with my solution. I just calculate the total cost of baskets present for the fruit types and the print minimum of themā¦

you are accessing an out of bound element here, causing undefined behaviour.

```
FOR(i,0,n){
tp += vec[i].second;
if(vec[i].first != vec[i+1].first){ //this may be out of bounds
s[j++] = tp ;
tp = 0;
}
}
```

simply pushing a nonsense value at the end, so that s always updates, got an AC.

Thanks

One more question . when i was checking some test cases on codechef IDE , Why there is no out of bound error

C++ assumes the coder is always correct. So it doesnāt bother checking. Thatās why itās a lot faster.if you want a runtime error, refer to :

It shows how to enable debug mode.

Okayā¦

āHidden Trapsā

By count, I meant the no. of baskets of that particular fruit. There can be a test case where the no. of baskets for a particular fruit may be > 0 but the total price is 0.

1

6 4

1 2 3 4 1 2

0 2 3 3 0 1

your code here is giving 3 as an answer but the actual answer is 0. As there are 2 baskets with fruit 1 and cost 0.

Please tell me why this code is giving wrong answer?

#include

using namespace std;

int main() {

int t,n,m,i,j,min;

cin>>t;

while(tā)

{

cin>>n>>m;

int f[50],p[50],q[50]={0};

int ans=0;

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

{

cin>>f[i];

}

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

{

cin>>p[i];

}

for(j=1;j<=m;j++)

{

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

{

if(f[i]==j)

{

q[j]=q[j]+p[i];

}

}

}

```
for(i=1;i<=m;i++)
{
if(q[i]!=0)
{
min=q[i];
break;
}
}
for(i=1;i<=m;i++)
{
if(q[i]<min && q[i]!=0)
{
min=q[i];
}
}
for(i=1;i<=m;i++)
{
if(q[i]==min)
{
ans=ans+min;
}
}
cout<<ans<<endl;
}
return 0;
