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.

Ex Input:
2, 17, ['7733', '4919', '637', '849', '5021', 'L', 'l', '537', 'z', 'r', 'Q', 'z', '4447', '65', 'L', '343', '1081', '1113', '3903', '405', 'f', 'X', '1955', '2985']
