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: 11, 15, ['7053', '5421', 'Q', 'S', '1309', '371', '8639', 'w', '7285', 'e', '1737', 'G', '5863', 'q', 'p', 'k', '2007', '3935', '9429', '5133', '5493', 'I', '1089']
