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: 5, 9, ['q', '1655', 'W', '543', '9317', '7215', '7485', '5691', 'r', '4421', '9783', 'R', 'H', 'u', 'J', '85', '6599', '519', 'B', 'h', 'M', 'B', '3537', 'Y', '5383', '8587']
Example Output: r1965584751277139
