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:
9, 11, ['I', '713', 'V', 'Z', '3693', '1861', '817', 'I', 'H', 'b', '9967', 'O', 'M', 'u', '7767', '853', '5445']

Ex Output:
9967bH
