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: 17, 23, ['6007', 'Q', '413', 'G', '9381', '2015', 'B', '5311', 'U', '2367', '2275', 'A', '3567', 'Y', 'I', '6633', 'u', '1125', '6115', 'y', 'G', 'b', '6515', '5023', '5331', 'r']
