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: 15, 17, ['a', 'h', '5911', '747', '9527', '5417', 'Z', 'l', 'n', '7855', '6539', 'e', '7351', 's', 'K', '1559', '3037', 'T', '4089', '3549', '4831']
