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: 7, 10, ['B', '3815', 'A', 'B', 'm', '8431', 'X', 'S', 'c', 'E', 'y', 'i', '8995', 'K', '6059', '1461', '7301', 'u', 'f', '6597', '3193', '3089', '3309']
