while(t--){
    int n,u,d;
    cin>>n>>u>>d;
    int c=1;
    int j=1;
    vector<int> h(n);
    for(int i=0;i<n;i++){
        cin>>h[i];
    }
    for(int i=1;i<n;i++){
        if(h[i]-h[i-1]<=u){
            c++;
        }
        else if(h[i-1]-h[i]<=d) c++;
        else if(h[i-1]-h[i]>d && j==1){
            c++;
            j--;
        }
        else
