Reason step by step, create the file `/app/answer.txt`, and put your final answer there.\n Your answer should be a single integer from 1 to 999 inclusive.\n\n Alice and Bob play the following game. A stack of $n$ tokens lies before them. The players take turns with Alice going first. On each turn, the player removes either $1$ token or $4$ tokens from the stack. Whoever removes the last token wins. Find the number of positive integers $n$ less than or equal to $2024$ for which there exists a strategy for Bob that guarantees that Bob will win the game regardless of Alice's play.\n"},"uuid":"d49a39d1-1970-4b96-a3ad-80c436634dc6","times
