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: 5, 12, ['7745', 'U', 'H', '6603', '3997', 'C', '9985', '7383', '3853', 'D', '6269', 'r', '3309', 'a', '7801', 'i', '5357']
