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, 13, ['d', 'H', '5121', 'm', 'g', 'D', '4897', 'U', 'O', '8943', 'Y', 'D', 'u', '8919', 'D', 'M', '7485', '5363', 'Y', 'h', '789', '1273', '7523', '3165', 'A', '7915']
