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: 3, 7, ['Y', '5629', 'J', 'Q', '7907', 'C', '2053', 'e', 'L', '5165', '6687']
Example Output: 2053C7907QJ
