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.

Example Input: 6, 15, ['7969', 'z', '7061', 'J', 'T', '7917', '7225', '7907', '8333', 'U', 'w', 'Y', '4729', '2461', 'X', 'k']
