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: 1, 5, ['2861', '8639', '483', 'i', 'M', 'U', '6293', '5293', 'Q', 'y', '6117', '2335', 'g', 's', '4485', 's', 'o', 'P', 'O', '2745', '9817', '3335']
