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: 2, 15, ['4879', 'Z', 'o', 'T', '7235', 'i', 'n', '1291', '3425', 'L', '8661', 'M', 'o', '6529', 'o', 'K', 'W', 'R']
Example Output: o6529oM8661L34251291ni7235ToZ
