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: 10, 11, ['7767', '1581', 'W', '19', '7233', 'm', 'W', '7201', '9689', '77', '3469', 'v', '1279', 'x', 'N', '7735', '7359', '3779', '9503', 'X', '411', '5877', 'k', '4747', 'Y', 'O', '7869', 'Y', '3439']
