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: Consider Input: 21, 21, ['i', 'p', 'i', '3553', '1009', '2477', '2835', '8841', 'A', '5679', 'L', '4213', 'J', 'H', 't', '8047', 'r', 'E', '1497', 'L', 'c', '5859', 'o', 'l']

Output: c
