Definition: 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: 3, 13, ['a', 'F', '3449', 'M', '5181', '2989', '9531', 'D', 'x', 'U', 'b', 'T', '1135', 'W', '9319', 's', '6925']
