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: 2, 3, ['I', 'w', '5079', '817', 'A', '7115', '8191', '7087', 'C', 'n', 'z', 'H', 'P', '7005', '3663', '8941', '6471', '6531', '2247', '7319', 'B']
