Leaky ReLU

题面

Implement a program that performs the leaky ReLU activation function on a vector of floating-point numbers. The leaky ReLU function is defined as:

f(𝑥) = { 𝑥 if 𝑥 > 0 ; 𝛼𝑥 if 𝑥 ≤ 0 }, where 𝛼 is a small positive constant (0.01 in this problem).

Implementation Requirements

• External libraries are not permitted
• The solve function signature must remain unchanged
• The final result must be stored in vector output
• Use 𝛼 = 0.01 as the leaky coefficient

Examples

Example 1:

Input:  x = [1.0, -2.0, 3.0, -4.0]
Output: y = [1.0, -0.02, 3.0, -0.04]

Example 2:

Input:  x = [-1.5, 0.0, 2.5, -3.0]
Output: y = [-0.015, 0.0, 2.5, -0.03]

Constraints

• 1 ≤ N ≤ 100,000,000
• -1000.0 ≤ input[i] ≤ 1000.0
• Performance is measured with N = 50,000,000
