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.

Example Input: 1, 6, ['4937', 'x', '6497', 'l', 'n', 'V']
Example Output: Vnl6497x4937

Example Input: 2, 3, ['4733', '2731', '1023']
Example Output: 10232731

Example Input: 3, 5, ['u', 'G', '7913', '3395', '8527']
Example Output:
852733957913
