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:
2, 9, ['3715', '8919', 'o', 'R', 'S', '1351', '7335', 'A', 'o', 'W', 'z', 'd', '4609', 'd', 'F', 'N']

Ex Output:
