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, 7, ['z', '2235', 'B', 'E', 'u', 't', 'p', 'h']
Example Output: p

Example Input: 6, 16, ['a', '511', '1179', 'L', 'g', '6341', 'z', '3677', '4357', 'T', 'F', '7461', 'U', '7393', 'p', 'k', '287']
Example Output: kp7393U7461FT43573677z6341
