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, 13, ['P', 'z', 'H', '9395', '6419', '1593', '5635', 'X', 'w', 'a', 'o', '7851', 'p', 'A', '6693', '237']
Example Output: p7851oawX5635159364199395HzP
