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: 2, 19, ['j', '7679', '6729', '319', '9397', '3963', '5687', '5555', 'L', 'P', '1429', '1885', '1489', '4641', '6755', 'f', 'E', '8993', '1735', '5147', 'g', 'q', '4773', 'y', 'k', '3599', 'S']
