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: 16, 17, ['6657', '951', '3481', 'c', '939', '199', 'X', '8493', '7665', '1', 'D', '5363', '4345', 'c', 'P', 'U', 'I', 'M', '7591', 'd', '6765', '9235', '3061', 'K', '1657', 'o', 'u', 'a']
