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: 8, 13, ['7725', '8399', 'P', '9663', '4059', '5265', '1703', 'I', 'E', '1587', 'X', 'N', 'W', 'K', 'j', 'R', 'P']
Example Output: WNX7851EI
