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, 3, ['u', 'k', 'M', '7101', 'U', 'f', 'L', '653', '2863']
Example Output: Mku

Example Input: 2, 2, ['P', '1275', '4841', 'J']
Example Output: 1275

Example Input: 1, 8, ['R', '8309', '4715', 'V', 'N', '3713', '5533', 'o']
Example Output:
