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: 2, 12, ['d', 'a', 'G', 'm', 'W', '3637', 'X', '2133', 'O', 'R', 'K', '4225', 'P', '4595', 'H', '7557', 'G', '5093', '3405', 'g', 'q', 'W', '801', '5119']
