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: 1, 8, ['L', '9991', 'J', '5871', 'X', '1467', 'V', 'p', '9893', 'S', '7419']
Example Output: pV1467X5871J9991L
