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, 5, ['1817', '3607', 'J', 'p', 'H', '639', '601', 'f', '8613', 'q', '1999', '4447', 'g', '8449', '1125', '1103', 'Y', 'p', 'Z', '5707', 'p', 'Q', 'a', '3889', 'Z', '5393', 'd', '9023', '4153']
Example Output: HpJ70637181
