Reverse Array

题面

Implement a program that reverses an array of 32-bit floating point numbers in-place. The program should perform an in-place reversal of input.

Implementation Requirements

• Use only native features (external libraries are not permitted)
• The solve function signature must remain unchanged
• The final result must be stored back in input

Examples

Example 1:

Input: [1.0, 2.0, 3.0, 4.0]
Output: [4.0, 3.0, 2.0, 1.0]

Example 2:

Input: [1.5, 2.5, 3.5]
Output: [3.5, 2.5, 1.5]

Constraints

• 1 ≤ N ≤ 100,000,000
• Performance is measured with N = 25,000,000
