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: 8, 11, ['G', 'Q', '5527', '2067', 'Y', 'K', '8395', '1125', '4279', '3947', '1979', 'r', 'A', '3823', '3883', '4465', '3839', 'b', 'x', 'J', '4613', '49', 'K']
