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: 5, 15, ['w', '2537', 'F', '1739', '449', 'c', 'Z', '8147', 'g', '81', '385', 'K', 'D', '3209', 'c', '9935', '8215', '9897', 'Y', 'n', '5715', '6825', '7521', 'i', 'N', '7139', '1205', 'C', 'r']
