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, 10, ['H', 'k', 'T', '5261', 'h', 'o', '7563', '2021', '5989', '3451', 'n', '8751', '5545', 'j']
Example Output: 3451598920217563oh5261Tk
