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: 8, 10, ['l', '7437', '8763', 'i', '3635', 'O', '6275', '1121', 'h', 'Y']
Example Output: Yh1121

Example Input: 1, 3, ['M', '9885', 'k', '8111']
Example Output: k9885M
