In this task, you are given inputs 'i', 'j', and A, where 'i' and 'j' are integers and A is a list. A list is shown by two brackets and comma-separated numbers and characters inside, like ['1', '12', 'l']. You need to concatenate all elements of A from the ith element to the jth element, and then reverse the resulting string. 'i' and 'j' will be non-negative, and will always have a value less than the length of A. 'i' will always be less than 'j'. Perform the operations in order, i.e., do not reverse first and then concatenate.

Example Input: 2, 10, ['V', '7549', '4639', '3825', '4619', 'w', '7667', '557', 'L', 'z', '1883', 'k', 'j', 'o', 'p', '3945', 'u', 'l', '5637']
Example Output: zL7557667w9164528393649457
