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: 9, 27, ['J', '8305', 'e', '3983', 't', 'v', 'j', '5873', '7315', 'D', '9867', '1003', 'X', 'Z', 't', 'A', '1851', '5373', 'r', '6811', 'u', 'A', 'E', 't', 'R', '4339', '4501']
