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:
9, 10, ['3699', '2795', '241', '6127', 'Y', 'z', 'R', '8979', '55', '367', 'i', '4883', 'g', '5435', 'O', '2861', '3949', 'd', '877', 'M', 'E', 'V', 'q', '1033', '8793']

Ex Output:
