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: 12, 25, ['x', 'h', 'z', 'a', 'T', 'p', 'F', '1767', '5809', 'E', 'B', '4745', '8605', '2909', 'e', 'D', 'l', '2869', 'C', '1705', '7429', '8703', 'G', 'b', 'w']
