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: 1, 3, ['238', 'h', '92', 'U', '2799']
Example output: 92h238
Example explanation: Here, concatenating all the elements between the 1st element and 3rd element in reverse order gives '92h238'.
