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, 11, ['T', '4649', 'Y', 'y', '975', '1319', '6433', '2689', 'Z', '4697', '5155', 'z', '2077', '4739']

Ex Output:
5155
