Problem Constraints
1 <= Ai <=105
1 <= B×C <= 105

Input Format
First argument is an integer array A.
Second argument is an integer B.
Third argument is an integer C.

Output Format
Return 2D integer array.

Example Input
Input 1:
```A = [1, 2, 4, 8]
B = 2
C = 2
```

Input 2:

```A = [1, 2, 3, 4, 5, 6, 7, 8, 9]
B = 3
C = 3
```

Output 1:
```[[1, 2],
[8, 4]]
```

Output 2:

```[[1, 2, 3],
[8, 9, 4],
[7, 6, 5]]
```

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
