Generate all subarrays

Problem Description

You are given an array A of N integers. Return a 2D array consisting of all the subarrays of the array

Note : The order of the subarrays in the resulting 2D array does not matter.

Problem Constraints

1 <= N <= 100
1 <= A[i] <= 10^5

Input Format

First argument A is an array of integers.

Output Format

Return a 2D array of integers in any order.

Example Input

Input 1:
A = [1, 2, 3]

Input 2:
A = [5, 2, 1, 4]

Example Output

Output 1:
[[1], [1, 2], [1, 2, 3], [2], [2, 3], [3]]

Output 2:
[[1 ], [1 4 ], [2 ], [2 1 ], [2 1 4 ], [4 ], [5 ], [5 2 ], [5 2 1 ], [5 2 1 4 ] ]

Example Explanation

Explanation 1:
All the subarrays of the array are returned. There are a total of 6 subarrays.

Explanation 2:
All the subarrays of the array are returned. There are a total of 10 subarrays.

Output
