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: 15, 15, ['m', '5831', '8985', 'b', 'F', 'o', '7953', 'y', '6585', '6253', '3249', '3795', '2129', '3297', '965', '5763', 'x', 'H', 'X', '2789', 'x', '6777', 'g', '5907', 'c', 'd']
