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: 17, 18, ['3655', 'P', '6759', 'n', '9633', '1717', '9761', 'l', 'y', '6197', '5581', 'R', 'J', 'D', '1767', '8773', '3107', '3931', '8489', 'K', 'f', '6167', 'm', 'W', '6623', '7407']
