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, 23, ['n', 'i', '4961', 'f', 'p', 'Q', '8115', 'F', '4767', 'J', 's', 'y', '7553', 'n', 'O', 'B', 'u', 's', '1209', 'w', 'D', 'C', '2481', '6015']
