Vector Addition

题面

Write a GPU program that performs element-wise addition of two vectors containing 32-bit floating point numbers. The program should take two input vectors of equal length and produce a single output vector containing their sum.

Implementation Requirements

• External libraries are not permitted
• The solve function signature must remain unchanged
• The final result must be stored in vector C

Examples

Example 1:

Input:  A = [1.0, 2.0, 3.0, 4.0]
        B = [5.0, 6.0, 7.0, 8.0]
Output: C = [6.0, 8.0, 10.0, 12.0]

Example 2:

Input:  A = [1.5, 1.5, 1.5]
        B = [2.3, 2.3, 2.3]
Output: C = [3.8, 3.8, 3.8]

Constraints

• Input vectors A and B have identical lengths
• 1 ≤ N ≤ 100,000,000
• Performance is measured with N = 25,000,000
