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: 7, 16, ['J', '8449', '9507', '6729', '1979', 'm', 'W', '8217', 'E', 'r', 'J', '7923', 'n', 'A', 'M', '6715', 'F', 'b', 'I', '1375', '6587', 'h', '3101', 'N']

Output: 6715MAn7923JrE8217W
