Interleave Arrays

题面

Write a GPU program that interleaves two arrays of 32-bit floating point numbers. Given two input arrays A and B, each of length N, produce an output array of length 2N where elements alternate between the two inputs: [A[0], B[0], A[1], B[1], A[2], B[2], ...]

Implementation Requirements

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

Examples

Example 1:

Input:  A = [1.0, 2.0, 3.0], B = [4.0, 5.0, 6.0]
Output: [1.0, 4.0, 2.0, 5.0, 3.0, 6.0]

Example 2:

Input:  A = [10.0, 20.0], B = [30.0, 40.0]
Output: [10.0, 30.0, 20.0, 40.0]

Constraints

• 1 ≤ N ≤ 50,000,000
• Performance is measured with N = 25,000,000
