A *k-subsequence* is defined as follows:

- It is a subsequence of
*consecutive* elements. - The
*sum of its elements*, **s**, is evenly divisible by **k** (i.e.: **s % k = 0**).

Complete a function called *kSub* with two parameters: an integer, **k**, and an array of integers, **nums**, of size **n**.

**Output Format :**

Return the number of *k-subsequences* as an integer.

**Sample Input:**

```
3
5
1 2 3 4 1
```

**Sample Output:**

```
4
```

**Explanation:**

Below are the four consecutive subsequences with sums that are evenly divisible by **k** = 3:

```
3
1 2
1 2 3
2 3 4
```
