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: 3, 14, ['v', '1211', 'q', '4877', '2391', '5519', 'W', '2051', 's', '9685', '2313', '6689', '8865', '9717', 'R', '3559', '8569']
