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: 3, 14, ['a', '4703', 'I', 'q', 'P', 'J', '8387', 'I', '3277', 'p', 'X', '8093', 'u', '5989', 'F', 'y', 'X', 'm', 'R', '1003', 'o']
Example Output: 5989u8093Xp3277I8387JPqI
