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: 4, 12, ['2333', '8325', 'J', '515', '7783', 'f', 'Y', '7191', 'T', '4365', 'n', '7317', 'q', 'M', '8323', 'B', 'B', 'q', '5799', '2717', 'c', 'I', 'B', 't', 'U']
