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: 15, 23, ['s', '3465', '4557', '4483', 'A', '6025', 'z', '37', '9133', 'w', 'g', '9111', '8131', '1797', '6091', '3045', 'x', 'n', 'E', 'x', 'D', 'w', '7911']
