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: 20, 23, ['2689', 'J', 'G', '1125', 'h', '3165', 'B', 'I', 'J', 'd', '2815', '6181', 'y', 'w', '5553', '749', '7523', '1729', '8807', '3097', '5521', '577', 'x', 'T', '3565', 'N', '6015', '603']
