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.

Ex Input:
1, 23, ['8861', 'p', 'j', 'z', '1075', 'K', '4161', '1633', 'W', '2613', 's', '8601', 'e', 'n', 'R', 'H', '4839', 't', '8051', 'V', 'r', 'h', '1987', '483', '2753', '7295', '5601', '5935', 'o']

Ex Output:
