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:
13, 23, ['4763', '2429', 'l', '3433', 'W', '4653', 'n', '3171', '555', 'N', '6615', 'G', 'E', 's', 'l', '5877', '7441', '9415', 'w', '5903', '8227', '89', '493', '7633']

Ex Output:
