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: 18, 20, ['D', 'q', 'H', 'l', 'l', '5325', 'n', '4453', 'F', '3517', '19', '2921', 'N', 'N', '7879', 'R', '1143', 'j', 'V', 'M', 'k', 'A', '8873', 'r', 'F', '9469', '957', 'M', 'B', '2863']
