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: 17, 19, ['j', 'K', '5229', 'g', '3977', '1071', '3887', '6445', 'w', '4323', '2093', 's', '3283', 'k', '1589', '7363', 'b', 'U', '6125', '7883', 'P', '2479', 'W', '9003', '3983', 'h']
