My output is not coming out right

I am unable to place ", " between 2 elements on the same level. Here’s my code: https://ide.codingblocks.com/s/654084

Hi @mitrapranav0027_5d705c8b616e0add,

You could modify the function like this,

cout<<"[";
    while(!q.empty()) {
        node*f=q.front();

        if(f==NULL) {
            q.pop();
            cout<<"]";

            if(!q.empty()) {
                cout<<", [";
                q.push(NULL);
            }
        }
        else {
            cout<<f->data;
            if(f->left) {
                q.push(f->left);
            }

            if(f->right) {
                q.push(f->right);
            }

            q.pop();
            if(q.front() != NULL){
                cout<<", ";
            }
        }

    }
