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, 11, ['N', '5989', '9485', '1955', '4841', '8403', 'f', 'M', '3261', '9581', '8083', '5201', '6391', 'h', 'C', 'O', '6361', '4033', '9121', '9825']
