Q: 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.
13, 26, ['l', 'E', '4509', 'A', 'h', '5321', '6847', '7985', 'i', 'x', '5421', 'N', 'K', '419', 'a', '2965', '4665', 'R', '6849', '1979', 't', 'd', 'F', '7021', 'y', '7795', 'r']
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
