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: 10, 17, ['415', 'y', '2697', 'v', '8571', 'W', 'F', '7681', '1593', 'c', '3935', 'Q', 'c', '725', '8703', 'J', '8607', 'l', 'Q', 'i']
