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: 9, 16, ['I', 'j', 'I', 'W', 'f', '5511', '1989', 'K', '423', '593', '6283', '2699', '8375', '8757', '9561', 'o', '3371', '6349', 'N', '4835']
