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: 13, 21, ['s', 'L', '7365', '7481', 'n', 'L', '1965', 'k', 'l', 'u', '1617', '5225', '4161', 'e', 'E', 'G', 'x', '6827', 'I', 'F', '5811', 'f', '1169', 'P', '5701', '4043', '6195', 'w', '7495', '4419']
