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, 14, ['3061', '2055', '5409', '97', '8729', '695', 'w', 'g', '9557', '6973', '3061', '8693', 'a', '611', '7465', '7101', '1199', '2371', 'k', 'C', '2931', '6369', '2765', 'z', '4593', '881', 'B', 'Q']
