Definition: 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.
Input: 11, 15, ['3491', 'u', '4737', 'q', '4857', 'D', '7541', 'H', '9519', 'W', 'C', '1103', 'f', '9211', '3507', '9873']
