Write a function as seen in the photo. Do NOT use any loops

**Problem 3:**

Write a function `softMax(x)` to return a 1D array of softmax function values 

\[
f_i = \frac{e^{x_i - m}}{\sum_{j=0}^{K-1} e^{x_j - m}}
\]

for \( i = 0, 2, \cdots, K-1 \), where \( x \) is a 1D array of \( K \) floats, \( x_i \) is the \((i+1)\)-th element of array \( x \), and \( m \) is the largest element in array \( x \).

**Sample:** If `z = np.array([10, 5, 8])`, then `softMax(z)` returns `array([0.876, 0.006, 0.118])`.

---

```python
pass

def softMax(x):
    z = np.array([10, 5, 8])
    softMax(z)
```

**Explanation:**

This exercise describes how to implement the softmax function, which is a common activation function in machine learning. The formula involves computing exponential values and normalizing them by their sum, adjusted by the maximum value \( m \) to improve numerical stability. The given code, however, only includes a placeholder `pass` and an example array `z` is passed into the not-yet-defined `softMax(z)` function.
