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: 2, 19, ['L', 'I', 'W', 'v', 'o', 'T', 'W', '5917', '7249', 'X', '9349', '2457', 'H', '479', '1485', '6015', 'b', 'd', 'p']
