why is this giving 0 as the answer?
#include

using namespace std;

int main() {

int n;

cin>>n;

int a[1000];

for (int r=0;r<n;r++){

    cin>>a[r];

}

int msum=0;

int csum;

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

    for(int j=i;j<n;j++){

        csum=0;

        for (int k=i;k<=j;k++){

            csum=csum+a[k];

        }

        if (csum>msum){

            csum=msum;

        }

        

    }

}

        cout<<msum;

        return 0;
