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.

Input: Consider Input: 14, 15, ['b', '863', '5093', '7589', '6635', 'X', '863', '8197', '3571', 'u', 'J', '1331', 'M', 'z', '9965', '3989', '2677', 'm']

Output: 9965z
