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, 4, ['K', '9877', 'B', '4495', '7627', 'z', 'o', '4203', '3', '3005', '3125', 'i', '8305', 'V', 'l', '2733', '6667', 's', 'B', 'H', 'a', 'G', '3527', '6991', '269', 'F', 'C']
