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, 25, ['4889', 'Y', '8701', 'y', 'w', 'D', '8021', '4867', 'V', '7373', 'H', 'j', 'W', '417', '6887', '7559', '435', 'v', 'v', 'D', '6075', 'N', 'w', 'p', '3673', 'H']
