Neural Network Implementation

Implement a simple neural network capable of performing forward propagation. Assume the input layer has 4 neurons, the hidden layer has 3 neurons, and the output layer has 2 neurons. You need to define the network's architecture and parameters, and implement the forward propagation function, assuming ReLU as the activation function. Provide test cases. Example Input 1 2 3 4 0.2 0.4 0.6 0.8 0.1 0.3 0.5 0.7 0.9 0.11 0.13 0.17 0.1 0.1 0.1 0.3 0.3 0.3 0.2 0.2 0.2
