Subarray Problem

 1. You are given an array of size 'n' and n elements of the same array.

2. You are required to find and print all the subarrays of the given array. 
3. Each subarray should be space seperated and on a seperate lines. Refer to sample input and output.

Input Format

A number n
n1
n2
.. n number of elements

Output Format

[Tab separated elements of subarray]
..
All subarrays

Constraints
1 <= n <= 10
0 <= n1, n2
 .. n elements <= 10 ^9
Sample Input
3
10
20
30
Sample Output
10	
10	20	
10	20	30
