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: 11, 18, ['3393', '2681', 'Y', '67', '3215', 'x', '6619', '5133', '1857', '159', '9157', '4181', '8155', 'b', '3225', '5197', 'f', '6715', '1659', 'o', 'Z', 'k', '23']
