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: 16, 19, ['l', '4399', 'n', '6761', '6155', '65', 'j', 'a', '6399', '6889', '4519', '9279', '7191', '1005', 'l', 'b', '9343', '4955', 't', '5673', 'E', 'f', '2195', '279']
