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, 8, ['9583', '3923', 'x', 'H', '7663', 'J', '4401', 'J', '3299', '137', '5981', 'r', 'r', 'm', '3333', '3283', '6973', 'r', '8917', 'g', '797', 'K']
Example Output: J4401J7663Hx3923
