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.

Input: Consider Input: 5, 6, ['A', 'v', 'x', '2047', '5955', 'l', '4845', '1347', 'i', 'm', 'W', 'h', 'w', '4483', '1509']

Output: l5595
