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: 6, 10, ['P', '8531', '6115', '4161', '4429', '569', '8581', '6081', '7303', 'p', 'z', '7307', 'a', 'A']
Example Output: p730360818581569
