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: 4, 14, ['U', 'V', '1179', '873', '2009', 'D', 'w', '8755', 'R', '5147', '9803', 'p', 'j', '1401', '6241', '8259', '2909', 'Y', '8539', '9451', '267', 't', 'W', '2163', '9839', '6457', '6799']
