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: 16, 23, ['339', '7007', '8911', '3091', '5083', 'y', 'h', 'y', 'X', 'w', '3263', '7733', 'R', '4261', 'v', '6781', '1063', 'e', 'q', '9553', 'u', '343', '2077']
