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: 5, 10, ['6459', '4015', '2033', 'n', '6853', 'a', '8037', 'H', '9691', 'h', '8847', '4333', '4785', 'y', '1227', 'd', 'm', '2247', 'V', '6923', '4071', '3237', 'D']
