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.

Ex Input:
24, 27, ['F', '9479', '605', 'w', '5935', '7635', 'k', 'e', 'm', '8999', 'M', 'f', 'z', 'r', '8031', '5693', '7125', '8559', 'X', '1231', 'B', '6687', 'a', '8881', '3377', 'c', '37', 'V', '1767', 'I']

Ex Output:
37c33778881
