In this task, you are given inputs i, j, and A, where i and j are integers and A is a list. You need to find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output the resultant 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 concatenate the elements and then reverse the string.

Example Input: 3, 12, ['n', '1995', '9023', '6583', 'e', '1551', '1189', '451', 'I', '9021', '9823', '2777', 'u', '9695', 'p', 'C', '3255', '79', '6763', 'a']
Example Output: 277798239021I45111891551e65839023
