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: 11, 12, ['A', 'W', '3955', 'n', 'C', '9699', '8239', 'q', '3219', '5119', '4021', 'd', 'w', 'v', 'v', 'k', 'a', '4305', '9353', 'j', 'k', '9939', '5353', '4633', 'Y', 'r', '9367', '427']
