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: 8, 16, ['O', 'e', '5857', '6759', '9787', 'e', 'j', '9173', 's', '4135', 'j', 'I', 'g', 'f', '2129', 'n', '3337']
Example Output: n2129fgIj4135s9173
