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: 1, 16, ['I', 'Y', '3689', 'q', '1755', 'U', 'J', '597', '2235', '1435', 'b', 'd', '6791', 'O', '8087', '2239', '4529', 'E', '3549']
