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: 18, 23, ['V', 'Q', 'w', '677', 'o', '7209', '4807', 'x', '575', '2597', '2969', 'm', 'K', '8425', 'k', 'F', 'G', '4621', '2729', '3233', '6621', 'V', 'j', '6043', 'o', 'm', '3969', '5681', '3231']
