@function_of_zero

void eraser(int k){
    pair x,y;
    x=split(root,k);
    y=split(x.b,k+1);
    y.a=merge(son[y.a][0],son[y.a][1]);
    merge(x.a,merge(y.a,y.b));
}

改成

void eraser(int k){
    pair x,y;
    x=split(root,k);
    y=split(x.b,k+1);
    y.a=merge(son[y.a][0],son[y.a][1]);
    root=merge(x.a,merge(y.a,y.b));//这里加了一个root=
}

然后加了个快读，吸了一口氧，就过去了
