GAIC Math 2024 Problem 135

  • Answer

Let nn be a positive integer. Now, a frog starts jumping from the origin of the number line and makes 2n−12^{n}-1 jumps. The process satisfies the following conditions:

(1) The frog will jump to each point in the set {1,2,3,⋯ ,2n−1}\left\{1,2,3, \cdots, 2^{n}-1\right\} exactly once, without missing any.

(2) Each time the frog jumps, it can choose a step length from the set {20,21,22,⋯ }\left\{2^{0}, 2^{1}, 2^{2}, \cdots\right\}, and it can jump either left or right.

Let TT be the reciprocal sum of the step lengths of the frog. When n=2024n=2024, the minimum value of TT is _____.
