Definition: 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.
Input: 9, 20, ['y', 'u', '1019', 'y', 'p', 'w', 'g', 'E', 'T', '2491', 'E', 'c', '7205', 'd', '2723', '3771', '7951', '8603', 'V', '9541', '4467', '2461', '4825', '7041', '5311', 'H', 'i', 'Y', 'Z', 'a']
