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: 27, 28, ['k', '2839', 'e', 'j', 'A', '5649', 'N', '2829', 'u', '6889', '9691', '6695', '9849', '8171', 'a', 'D', '1887', 'Q', 'P', 'H', 'n', '6333', '1491', 'U', '5313', 'A', '699', '665', 'N', 'q']

Output: 566996
