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.

Example Input: 7, 11, ['2019', 'j', 'B', '1079', '2647', 'I', 'e', '6891', '353', '6495', 'F', '8823', 'U', 'b', '8185', '8305', '2217', '8373', '1951', 'L', '9655', '5247', '8033', 'b']
Example Output: F64953536891e
