ReLU

题面

Implement a program that performs the Rectified Linear Unit (ReLU) activation function on a vector of 32-bit floating point numbers. The ReLU function sets all negative values to zero and leaves positive values unchanged:
ReLU(𝑥) = max(0, 𝑥)

Implementation Requirements

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

Examples

Example 1:

Input:  input = [-2.0, -1.0, 0.0, 1.0, 2.0]
Output: output = [0.0, 0.0, 0.0, 1.0, 2.0]

Example 2:

Input:  input = [-3.5, 0.0, 4.2]
Output: output = [0.0, 0.0, 4.2]

Constraints

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