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: 4, 16, ['i', '6411', '4139', '4653', 'M', '2895', 'p', 'P', '7901', 'w', '1559', '5923', 'U', '8351', 'A', '5861', '421', 'l', 'c', 'f', '3845', '9107', '2529']
