<prompt> Given the following array: show all the possible subarrays1, 2, 3, 4  <response>: A subarray is a contiguous part of an array. An array of length n has nn12 possible subarrays. For the given input 1, 2, 3, 4, we have the size of the array as 4. Thus, there are 4412 10 possible subarrays. The subarrays of 1, 2, 3, 4 are:12341, 22, 33, 41, 2, 32, 3, 41, 2, 3, 4
