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: 19, 23, ['703', 'A', 'u', 'Y', 'x', 'z', '9485', '8757', '5175', 'Y', 'p', 'b', 'n', '5227', 's', 'k', 'Y', 'f', 'c', '5601', '9609', '3881', '6725']
