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: 2, 12, ['i', 'p', 'J', '525', 'Z', '2099', 'e', 's', 'L', 'c', '3463', '6209', '7285', 'X', 'J', 'g', 'H', '6547', 'N', '6331', '3163']
