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: 13, 15, ['I', 'y', '3037', 'i', 'I', 'x', 'r', 'i', 'g', '1141', 'z', '8639', 'v', 'p', '7901', 'A', 'e', '7599']
Example Output: 1097pv
