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: 7, 13, ['7405', '2017', '1757', 'Y', '3515', 'J', 'Z', '7447', 'X', '6579', 'o', '489', 'N', '1603', 'N', '273', '1345', '6161', 'x']
Example Output: N489o6579X7447Z
