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, 27, ['S', 'p', '2923', '8217', 't', '9837', 'W', '877', 'p', '7215', '3653', 'F', 'k', '1783', 'L', 'j', 'J', '3457', '8285', 'W', 'Z', 'O', 'u', '6173', 'I', 'S', '6349', '5275', 'r', '3833']
