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: 8, 15, ['i', 'j', 'v', '8109', '793', 'N', 'H', 'L', '2057', '7463', 'o', 'D', '8261', '3399', 'x', '8341', '3501', '5279', '9133', 'D', '4049']
