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: 3, 11, ['s', 's', 's', '4831', 'a', 'a', '2987', '2331', '5611', '359', '2115', '1161', 'P', '5155', '7697', '6703', '9709', 't', '3651', 'A', 'b', '5253', 'Q', '1697', 'd', '5513', '5329']
