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, 13, ['s', '8529', 'p', 'm', '7059', 'j', 'C', '2863', '1513', '7099', 't', 'f', 'D', '6475']
Example Output: Dft709915132863
