# Exercises: Pseudo-Random Generator

Write a code to generate **30 pseudo-random integers** in the range **\[1...10]**, starting from certain **entropy**, taken as input, using **HMAC key derivation**.

From the **entropy** generate a **seed** (256-bit binary sequence) using **SHA-256**:

```python
seed = SHA256(entropy)
```

Generate the **n**-th random number by the formula:

```python
1 + HMAC-SHA256(n, seed) % 10
```

Print the numbers at the output, separated by space.

Sample **input** and corresponding **output**:

|             |                                                                   |
