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: 4, 7, ['v', 'd', 'J', '2685', '3099', '6043', '3371', 'l', 'X', 'G', '2513', '7637', '215', 'H', '6551', 'u', '2699', '3091', '6263', 'J', '3709', '7337', 'y', 'o', 'F', '2669']
