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: 1, 3, ['o', 'o', '4511', '9203', '6071', 'Q', '5337']
Example Output: 1154oo

Example Output: 5372

Example Input: 2, 2, ['2963', '3967', 'M', 'K', '8987', '8051', 'G', 'Q', 'g', 'h', '4489', 'X', 'H', 'o', 'v', '6469']
Example Output:
