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, 24, ['U', '505', 'E', '763', 'a', 'w', '4291', '2349', '4049', 'v', '6135', 'a', '6141', 'H', 'M', '53', 'R', 'q', 'G', '2945', 'e', 'w', 'v', '643', '4937']
