This is a pathological level that has no normal significance limit, such as: (1-1) (1-1) .. (1-1) ... = 0 1 (-1 1 (-1 1 1) (-1 1) ... = 1 according to 1 x ... x^n .. = 1/(1-x), although the convergence domain (-1,11 ), But to get (-1) in 1/2, it is another answer in the advanced tutorial of mathematical analysis, you should have a strict definition of this pathological level and The result is unique. But I don't know about this knowledge. You can find relevant information.

Euler's algorithm is correct. The probability of 1 and 0 value of S is equal, just like you and your brother to keep a 1 -dollar coin together. If you keep it for a day, you and your brother owns this coin. The value is half a person, which is 1/2.

IsmaelIf you do not exist, that is, the level of level divergent
