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, 6, ['e', '4767', '8447', 'e', 'P', '7453', 'i', 'I', 'z', '415']
Example Output: 7453Pe

Example Input: 4, 4, ['8643', '8469', '9265', 'i', 'P', '3633', 'A', 'g', 'l']
Example Output: i

Example Input: 16, 19, ['7225', 'W', '8757', 'z', '7865', '4769', 'C', 'N', 'B', 'X', '6443', '8213', '1775', '8923', '9755', 'O', 'M', '6369', '9559', '6883', '6477']
Example Output:
