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: 9, 12, ['479', 'b', '9573', 'e', 's', '8247', 'A', 'x', 'D', '1299', '3053', '8455', 'e', '929', 'I', 'P', '9299', '9041', '2595', '2503', '8603']
