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: 10, 16, ['H', 'f', 'I', '1567', 'Y', 'z', '4665', 'z', 'Y', 'x', '2189', '5567', 's', '3903', '1749', '3603', '4787', '3091', '9549', '91', '2063']
