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, 7, ['H', 'I', 'B', '6833', 'a', '7477', '8817', 'd', '4545', '779', 'F', '3265', '1819', '9317', '879']
Example Output: 88177477a6833
