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.

Example Input: 8, 10, ['1431', '7383', 'n', '867', '6287', 'g', '4183', '1323', '3899', 'G', 'l', 'd', '1375', 'f', '8839', '4151', 't']
Example Output: G38991323
