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: 24, 28, ['163', 'Z', 'a', '9495', 'b', '4971', '8615', '3927', 'J', 'K', 'W', '7043', '7187', 'N', 'J', 'z', '3137', 'b', 'K', '235', 'p', 'z', 'i', 'u', 'x', '9129', 'w', '6621', 'I', 'D']
