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: 12, 16, ['g', '9469', 'K', 'F', '6349', '207', 'V', 'J', 'D', 'o', 's', '1527', 'G', '7793', 'R', '3967', 'd', 'A', 'Y', 'F', 'f', 'P', '3479', 'M', '4785', '729', '6079', 'u', '2707', '8463']
