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, 19, ['4755', 'd', '7339', 'O', '9953', 'X', '8457', '2409', '2545', 'I', '1785', 'F', '9351', 'q', '6019', 's', '8391', '2043', '2951', 'W']
