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: 23, 25, ['x', '81', 'R', 'J', 'M', 'Q', 'O', 'C', '151', '9413', 'i', '9911', 'o', 'Y', '4317', '7647', '4951', 'f', '2301', '4455', '8923', 'x', 'H', 'x', 'x', 'a', '1749']
