You found on the Algoleaks site that each next integer on the sloth machine is generated using the formula . Source of x1, unluckly, on this site is not revealed. Your goal is to ensure the victory. Your program will receive on the input one integer — number of tokens You currently have or - 1 in case when game is over by some reason. If you received - 1, immediately exit your program with code 0 (otherwise you may get the random verdict from the system). Otherwise, if you received integer T > 0, print one integer between 1 and T, inclusively — your next bet. Dont forget to print end-of-line character and _flush_ the output. ## Input Your program will receive on the input one integer — number of tokens You currently have or - 1 in case when game is over by some reason. ## Output If you received - 1, immediately exit your program with code 0 (otherwise you may get the random verdict from the system).
