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, 16, ['1911', 'u', '1355', 'M', 'K', '1179', 'd', 'k', '5233', 'j', 'c', 'G', 'C', '4147', '6939', 'X', 'y', '4461']

Ex Output:
X69394147
