Why not passing testcase evenif in video same code run

#1

#include
using namespace std;
void mergee(int *a,int s,int e)
{

int i=s;
int mid=(s+e)/2;
int temp[100],k=s,j=mid+1;
while(i<=mid && j<=e)
{
if(a[i]<=a[j])
temp[k++]=a[i++];
else
temp[k++]=a[j++];
}
while(i<=mid)
{
    temp[k++]=a[i++];
}
while(j<=e)
{
    temp[k++]=a[j++];
}
for(int i=0;i<=e;i++)
    a[i]=temp[i];

}
void merge_sort(int *a,int s,int e)
{
int mid=(s+e)/2;
if(s>=e)
return;
merge_sort(a,s,mid);
merge_sort(a,mid+1,e);
mergee(a,s,e);
}
int main()
{
int n;
int arr[100];

cout << "Hello world!" << endl;
cin>>n;
for(int i=0;i<n;i++)
    cin>>arr[i];
merge_sort(arr,0,n-1);
for(int i=0;i<n;i++)
    cout<<arr[i]<<" ";
return 0;

}

hello Mihir,
image

a)value of n can be upto 2*10^5 so increase ur array size
b) remove cout<<“Hello World” u should only print those statements that are asked to print in output .

#include using namespace std; void mergee(int *a,int s,int e) { int i=s; int mid=(s+e)/2; int temp[100000],k=s,j=mid+1; while(i<=mid && j<=e) { if(a[i]<=a[j]) temp[k++]=a[i++]; else temp[k++]=a[j++]; } while(i<=mid) { temp[k++]=a[i++]; } while(j<=e) { temp[k++]=a[j++]; } for(int i=0;i<=e;i++) a[i]=temp[i]; } void merge_sort(int *a,int s,int e) { int mid=(s+e)/2; if(s>=e) return; merge_sort(a,s,mid); merge_sort(a,mid+1,e); mergee(a,s,e); } int main() { int n; int arr[100000]; cin>>n; for(int i=0;i<n;i++) cin>>arr[i]; merge_sort(arr,0,n-1); for(int i=0;i<n;i++) cout<<arr[i]<<" "; return 0; }
