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: 20, 26, ['6273', 'j', 'F', '9977', 't', '9857', '3497', '9419', '8223', 'w', 'M', '289', '6053', 'e', '8473', '7093', 'V', '1911', 'O', 'x', 'K', '6091', '9423', '1911', 'S', 'o']
