ReLU Activation

Apply the ReLU activation element-wise: $\max (0,x)\backslash max(0,x)$.

Implement solve(x).

Returns. Return a NumPy array of the same shape: negative values become $00$, others are unchanged.

Examples

Example 1

Input:

solve([-2, 0, 3])

Output:

[0, 0, 3]

Example 2

Input:

solve([[-1.5, 2.5], [0.0, -0.1]])

Output:

[[0.0, 2.5], [0.0, 0.0]]
