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, 10, ['s', 'c', 'C', 'a', 'S', '4909', 'V', 'P', '3457', '6461', '7783', 'F', '7279', '9637', '8919', '2403', '9123', 'w', 'U', '2803', '6671', '7945']
