Understand the problem
Restate the problem precisely. Interviewers reward candidates who pause, define the contract, and name the guarantees before coding.
Problem statement
Implement `pow(x, n)`, which calculates `x` raised to the power `n` (i.e., `xⁿ`).
Example
x = 2.0, n = 10 → 1024.0
Constraints
−100.0 < x < 100.0 · −2³¹ ≤ n ≤ 2³¹ − 1
