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: 5, 8, ['725', '7647', 't', '5381', 'I', 'U', '1107', 'z', '969', 'p', 'w', '3053', 's', 'N', 'R', '4651', '3381', '8699', 'F', '6013', 'P', 'e', '7855', '365', 'b']
Example Output: z1107UI
