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: 10, 18, ['f', 'I', '8607', '3543', '5447', 'T', '905', 'D', '4271', 'l', 'o', '2765', 'm', 'g', '855', '7499', '2313', '9869', '9705', '7449', '4713', 'm', 'd', 'w', 'C', '8285', 'E', 'j', 'A']
