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: Consider Input: 5, 18, ['4905', 'j', 'd', 'S', '8381', '233', 'r', 'i', 'P', '4971', 'Q', '1991', 'L', 'a', '9383', '931', 'T', 'g', '2561', 'L', '2757', 'e', '1829']
