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, 6, ['V', '1813', '3261', '2639', '3933', 'y', '9801', '5851', 'x', '6623', 'i', '2909', '7519', '7677', 'y', 's', '6803', 'u', '8493', 'O', 'V', 'C', '1969', 'w', 'Q', 'n', '7431']
