### Function Definition

**Function** `Func(A[], n)`

1.  Initialize `x = 0`
2.  **For** `i` from `1` to `floor(sqrt(n))` **do**
3.    Set `m = Random(i^2)`
4.    **For** `j` from `1` to `m^2` **do**
5.     **For** `k` from `1` to `j` **do**
6.      Update `x = x + im - jk`
7.     **End For**
8.    **End For**
9. **End For**
10. **Return** `x`

**End Function**

**Explanation:**

This pseudocode describes a function `Func` that takes an array `A[]` and an integer `n` as inputs and computes a value `x`. The function initializes `x` to zero and iterates over three nested loops, modifying `x` with each iteration:

1. The outer loop iterates over `i` from `1` to the floor value of the square root of `n`.
2. Within this loop, `m` is randomly assigned a value based on the square of `i`.
3. A second loop iterates `j` from `1` to `m^2`.
4. A third nested loop runs `k` from `1` to `j`.
5. Inside the innermost loop, the value of `x` is updated by adding the product of `i` and `m` and subtracting the product of `j` and `k`.

Finally, the function returns the computed value `x`.
