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:
11, 12, ['8873', 'N', '5397', 'v', 'B', '5841', '6213', '8827', '9869', '9449', 'b', 'c', '5441', 'T', 'V']

Ex Output:
