Array Manipulation

    I used the same approach but I am getting a segmentation fault in test cases 7-12. Can someone please explain me why?

    #include<iostream>
using namespace std;
int main()
{
    long n,m,a,b,k,sum=0,ans=0;
    cin>>n>>m;
    long int arr[n+1]={0};
    for(int i=0;i<m;i++)
    {
        cin>>a>>b>>k;
        arr[a]+=k;
        if(b!=n)
            arr[b+1]-=k;
    }
    for(int i=1;i<=n;i++)
    {
        sum+=arr[i];
        if(sum>ans)
            ans=sum;
    }
    cout<<ans<<endl;
}
