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, 10, ['Q', 'A', 'V', 'n', 'U', '8155', '3139', 'V', '7645', '3591', '5855', '3997', '565', '291', 'y', 'J', '1115']
Example Output: 35917645V3139
