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: 14, 20, ['5653', 'B', 'P', 'o', 'C', 'H', 'j', 'Z', '793', 'n', '2371', '2833', 'A', 'C', 's', '7853', 'v', 'c', 'N', '8797', '6925', 'E', 'J', 'A']
