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: 2, 4, ['N', 'I', 'J', '7741', 'l']
Example Output: 7741JI

Example Input: 1, 6, ['m', '6947', '9549', '8715', 'R', 'h', 'z']
