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: 2, 12, ['Z', 'E', 'i', '4687', '9341', '7787', 'A', '1787', '2239', '8317', 'B', '1061', '4327', '4807', 'X', 'G', '7687', 'F', 'J', '3629', '699', 'z', '2133']
