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: 21, 22, ['D', '3065', 'C', 'T', 'L', '2417', 'u', '3069', '893', '7253', '3741', '7931', '1171', 'l', 'j', '6897', '893', '5269', 's', '6397', 'p', 'X', '9633', '2371', 'R', 'X', 'a', '6563', '3249']
