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:
6, 13, ['7805', '3575', 'k', '8497', 'C', 'p', 'x', 'v', 'g', '1919', '397', '2757', '6027', 'u', '507']
