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, 12, ['3487', '3573', '4547', '5343', 'q', '8071', 'j', '6783', 'U', 'w', '7', '3281', '6303', 'J', '6685', 'u', '4401', '6259', 'N', 'i', '849', 'A', '6855']
