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: 5, 11, ['991', '4061', 'B', '1073', '6591', 'D', '2675', 'b', '9227', 'Y', '4821', 'i', 'T', 'G', 'k', 'z', 'E', '5651', 'S', 'o', '3773', '9643', 'W', 'a', '7951', '8743', 'b', 'B', 'W']
