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, 15, ['6749', '8811', 'm', '3179', 'w', 'X', '535', 'q', 'R', 'l', 'm', '8547', 't', 'U', 'o', 'P', 'Q', '655', '8445', 'b', 'A', '6715', 'U', '1457', '761', 'C', '3651']
Example Output: oUt8547mlRq
