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: 3, 16, ['815', 'I', 'A', '245', '83', '2629', 'B', 'J', '1827', 'H', '1247', '6191', 'S', 'Z', 'W', '1611', '9329', 'c', '8627', 'X', 'f', 'h', '8437', '3703', '8101', 'F']
