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: 12, 18, ['W', '9509', '3541', 'T', 't', 'Y', 'x', '9667', 'V', '7605', '7727', 'x', 'x', 'W', '3657', '2591', '9599', 'I', 'd', '6679', '1373', 'e', '6173', '8861', 'n', 'L', '5093', 's', '453']
