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: 3, 5, ['5011', '1189', 'H', 'F', '3857', '2423', '4235', '4323', 'o', 'd', 'o', '7583', '7413', 'm', '3467', '2445', '8919', 'a', '27', '4887', '3771']
Example Output: 3857FH
