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: 2, 4, ['N', 'I', 'J', '7741', 'l']
Example Output: 7741JI

Example Input: 2, 4, ['Z', 'a', '7659', 'E', '5827', '9553', 'w', 'a', 'i']
Example Output: E7659a

Example Input: 4, 6, ['8637', '5965', 'y', 'l', '4585', 'H', '6323', '2351', '6691', '427', 't']
Example Output:
