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: 4, 10, ['8271', '4307', '8053', '1105', '5247', '3183', '7629', '9177', 'b', 'c', 'b', '5657', 'U', 't', 'p', 'A', 'x', '3377', 'F', 'd', '3535', '6983', '5137']
