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: 11, 13, ['v', '781', 'B', 'a', '2951', '2767', '1639', '2891', 'F', 'l', '763', 'o', '595', '4363', 'X', 'g', '247', 'g', 'a', 'n', '4749']
