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: 12, 26, ['5183', 'K', 'e', '2683', 'C', 'S', 'I', 'u', '2477', 'n', 'O', 'a', 'i', 'd', '3249', 'c', '9577', 'x', 'h', '8515', '91', 'x', '1753', 'f', 's', 'h', '4939']
