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, 14, ['35', 'w', 'N', 'C', 'l', '9715', '8003', '9111', '6737', '5455', '5365', '859', '5979', 'U', 's', 's', '9599', 'g', '4577', '527', 'V', '5979']
