13.1.1 $\star$ In the first quadrant of the Cartesian coordinate system, number the points (lattice points) with integer coordinates in the following manner: (1) $(0,0)$, (2) $(1,0)$, (3) $(1,1)$, (4) $(0,1)$, (5) $(0,2)$, (6) $(1,2)$, (7) $(2,2)$, (8) $(2,1)$, (9) $(2,0), \cdots \cdots$ (as shown in the order of the arrows in the figure). Find the coordinates of the 2000th point.
Parse Note that the lattice points $(x, y)$ satisfying the conditions $0 \leqslant x \leqslant k, 0 \leqslant y \leqslant k$ total $(k+1)^{2}$. Considering the inequality $(k+1)^{2}$ 44, we know that the x-coordinate of the point is 44, and its y-coordinate is $44-(64-$ $45)=25$. Therefore, the coordinates of the 2000th point are $(44,25)$.
