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: 6, 12, ['R', 'x', '7035', 'Y', 'A', 'p', 'K', 'A', '5925', '915', '381', '6917', '8151', '8021', '4485', 'a', 'B', '6261', '2407', 'P', '6655', 'T', 'E', '691', '1995', 's', 'Z', 'd']
