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, ['W', 'e', '477', 'c', '4715', '1247', 'T', 'G', '1185', 'c', 'G', '3083', '7689', '5753', 'N', '3339', 'g', '3437', 'f', 'z', 'C', 'l']
