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: 3, 9, ['6141', 't', 'I', '9239', '747', 'k', 'o', '4329', 'b', 'a', '6943', 'n', '8749', 'u', '9367', 'q']
Example Output: b4329ok7479239I
