8.5 At the beginning of the game, the number 0 is written on the board. Two players take turns. On a turn, a player adds to the written number any natural number not exceeding 10, and writes the result on the board in place of the original number. The player who first obtains a four-digit number wins. Which of the players (the starting player or their opponent) has a winning strategy, i.e., a strategy that allows them to win regardless of how the opponent plays?
The first move: The beginner writes down the number 10 (the number 10 is the remainder of the division of the smallest four-digit number 1000 by 11). Next, if the second player adds the number $\mathrm{a}, 1 \leq \mathrm{a} \leq 10$, then the first player responds by adding the number $11-a, 1 \leq 11-\mathrm{a} \leq 10$. As a result, after two such moves, the number on the board increases by 11. Consequently, the numbers on the board after each move of the first player will be $10,10+11,10+2 \cdot 11, \ldots, 10+\mathrm{k} \cdot 11$. When $\mathrm{k}=99$, after the first player's move, the four-digit number 1000 appears for the first time.

From the above: The winning strategy belongs to the beginner.
