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: 6, 10, ['4631', 'q', '4689', 'w', '499', '3383', '8091', '7699', 'H', '6359', 'I', '267', 'v', '3295', 'H', '4815', 'u', 'o', '5023', 'n', '9471', '7435']
Example Output: 9536H996719083833
