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, 4, ['s', '4715', '8867', '5091', '435', 'z', '1765', 'H', '5107', 'F', 'F', 'i', '8923', '3693', 'F', '1211', '3111', '1669', 'm', 'c']
Example Output: 190576885174
