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: 3, 3, ['811', 'A', '8661', '3195', 'X', 'K', 'l', 'G', '1917', '647', '6381', '5365', '8681', 'm', 'c', '1099', 'h', '3423', 'r', 'N', '855', 'n', 'E', 'G']
