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.

Ex Input:
1, 8, ['V', '7207', '8907', '5875', '9755', 'S', 'b', '2569', 'U', '2959', 'H', '349', '6037']

Ex Output:
2569bS9755587589077207V
