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: 4, 9, ['7691', '4539', '3381', 'b', 'g', '9615', '8187', '177', '2473', '8579', '9739', 'C', 'v', 'q', '2879', 'Z', '6817', '5247', '5477', 'Y', 'w', '3981']
