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.

Ex Input:
11, 18, ['1575', 'E', '6695', '8459', '9887', '9997', '6613', '1957', '7569', 'm', '9375', '6379', '5561', '1307', 'E', '683', 'y', 'A', 'M', '1667', '397', '5181', 'x', '3903', 'O', '6377', 'Y']
