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: 14, 20, ['Q', 'j', '8215', 's', '9057', 'b', '8585', 'm', '6565', 'q', 'x', 'J', '2755', 'a', 's', '9421', '3433', 'x', '9505', '2699', '2343', 'Q', 'v', 'a', 'L', '2283', '6571', 'N', 'L', '3655']
