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, 15, ['6355', '1933', '9519', '3619', 'R', '4495', '6041', '5791', '7209', 'K', 'J', 'Y', 'n', '6789', '8173', '3805', 'P', '7609', '1525', 'c', 'H', 'C', 'T', 'c', '7667']
