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, 18, ['9763', '2983', '3517', 'p', 'A', 'm', '197', '8189', '1773', 'L', '791', '8489', 'y', 'e', 'T', 'c', '189', 'N', '7175', '9287', '6509', 'a', 'j', '5697', 'd']
