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: 15, 15, ['w', '5335', '5373', '2505', '9743', 'i', '6537', 'M', '5541', 'd', 'D', 'n', '6631', '6495', '1205', 'Q', 'S', '2443']
