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, 4, ['j', '2349', 'V', '4879', '8473', 'X', 'C', '2769', 's', '6297', '7723', '6009', 'I', '6385', '9161', '9179', '9785', '4965', '4479', '7323', '4685', '1891']
Example Output: 9784V9432j
