How to solve run time error

#1

I have written this code
but it is showing run time error for every case

#include
using namespace std;

int main()
{
int a[100],b[100],k,i,j,cs,ms,n;
cin>>k;
for(i=0;i<k;i++)
{
cin>>n;
for(j=0;j<n;j++)
cin>>a[j];
cs=ms=0;
for(j=0;j<n;j++)
{
cs+=a[j];
if(cs<0)
cs=0;
ms=max(cs,ms);
}
b[i]=ms;
}
for(i=0;i<k;i++)
cout<<b[i]<<endl;
}

Hey @ckaushik1799
Update array sizes according to the question

int a[100000],b[100000],k,i,j,cs,ms,n;
