Print all subarrays of a given array

Objec­tive:  Given an array write an algorithm to print all the possible sub arrays.

Example:

int [] a = {1, 2, 3};

Output: Possible subarrays –
{1}, {2}, {3}, {1, 2} , {2, 3}, {1, 2, 3}

Approach:

• Use nested loops.
• Outer loops will decide the starting point.
• First inner loops will decide the group size. Starting from 1 and goes up array size.
• Most inner loop will create the sub arrays and print it.
• See the code below for more understanding.
