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, ['G', 'e', '9885', '811', '9227', '613', 'Q', '537', '3171', 'W', 'h', '3253', 'J', 'd', 'p', '7695', '6649', 'x', 'W', '821', '6927', 'I', 'E']
