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: 15, 26, ['G', '3659', '8915', 'p', 'B', 'q', '8983', '8607', '2111', '7397', 'g', '245', '2677', '4249', 'K', 'g', 'M', 'F', '1895', 'v', '4943', 'B', 'P', '321', '8607', 'f', '6873', '8093']
