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: 10, 16, ['6231', 'o', '2273', 'm', 's', '7389', 'r', 'x', 'A', '6779', 'M', '5943', '6599', '9835', 'o', '3843', 'n', '9775', '8753', '9443', 'k', 'h', '4605', '195', 'R', 'Z', '4679', 'r', '59', '811']
