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:
14, 23, ['T', 'i', 'g', 'a', '709', '9323', '7203', 'p', 'i', '5131', 'l', '1817', 'y', 'v', 'j', 'p', 'D', 'o', 'd', 'L', 'J', '3011', '6039', 'P', '1349', '9021', '7379', 'P']
