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, 12, ['c', '83', 'X', 'H', '9555', '5741', 'A', 'i', 'd', '4583', '5009', '3057', '5989', 'P', 'J', '9395', '1639', '1521', 'c', '6447']
