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, 7, ['I', '2845', 'c', '9471', 'S', '8401', 'L', 'e', '2389', '845', '5379', 'x', 'n', '301', '9551', 'C', 'Q', 'p', '7047', 'C', '1129', 'z', '6241', '5957', 'n', 's', '9811', '1347', '7579', '8505']
