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, 11, ['9601', 'W', '3527', 'a', 'N', '5933', '8537', 's', 'E', 'l', '4879', '203', 'w']
Example Output: 4879lEs85375933
