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: 4, 12, ['4811', '5765', '695', '8003', '9709', 'Q', '3265', '1983', '8313', 'P', '7717', 'V', '5061', 't', '7263', 'z', 'a', '3807', '9269', '2399', '8537', 'O', 'd', 'j']
Example Output: V7717P831319833265Q97098003
