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, 17, ['9947', 'E', '6431', '967', 'u', 'n', '9743', 'N', '9551', '5911', 'Y', '7951', '1105', '9601', '7523', 'u', 'E', '4445']
