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: 10, 22, ['u', '697', '57', '5085', '2807', '6093', 'A', '3375', 'q', '5723', 'Z', 's', '759', '1923', '9061', '4653', '3173', '1893', 'P', 'e', 'U', '6645']
