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: 6, 25, ['j', '3957', 'O', 'B', 'S', '3577', '5401', '8901', '1845', 'B', '4655', '2965', 'w', '8321', '5481', '2799', '2563', 'z', '4853', 'l', '6495', 'a', 'o', '2537', 's', 'v', '2035', '2481']
