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: 1, 8, ['7975', '8543', '7605', 'Z', 'J', '4585', '5017', '3419', '1099', '4043', 'z', 'D', '4725', 'b', '7751', '9567', '4809', 'm', 'r', '1275', 'q', 'K']
