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: 16, 20, ['1635', 'M', '8163', '8861', '6687', '561', '4017', '3493', 'p', 'T', 'j', 'd', 'L', '7803', '3823', 'w', '959', '5445', 'V', '1769', '1313', 'S', 'L', 'D', 'C', 'h', 'q', 'd', 'X']
