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.

Example Input: 2, 13, ['J', 'C', 'a', '4063', 'l', 'w', 'i', '1337', '3987', '4975', '2361', '1127', 'I', 'L', '9219', 'v', 'A', 'A', 'p', '1775']
