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: 11, 12, ['N', '6665', '6543', 'Z', '1645', 'R', 'J', 'L', '879', '4731', '9505', '2705', '1329', '7227', '3951', '8277', '3709', '5893', 's', 'F', 'l', '5509', '565', 'T', 'K']
