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:
5, 10, ['3193', '1089', '3677', '2973', 'A', 'f', '3047', '6709', '4089', 'X', 'A', 'j', '5703', '2787', '2429', '9605', '6061', 'G', 'Y', 'b', '8741', '4199', 'f']
