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: 6, 14, ['g', '2513', 'K', '8351', 'i', 'A', '2243', '6941', 'v', '2931', '3803', '5177', 'r', 'F', '7435', 'x', 'j', 'U']
