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: 3, 10, ['q', '8815', '5453', 'n', '5103', 'X', 's', '9739', '1301', 'v', 'F', 'm', 'S', 'd', '6649', '2087', '4295', '8891', '5845', '577', 'I', 'U', '9195', 'E', 'o', '7229']
