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: 19, 28, ['8235', '9513', '5663', 'W', '6643', '4845', 'T', 't', 'o', 'x', 'y', '2793', '2127', 'N', 'C', 'a', 'f', 'P', 'T', 'z', '6175', '5927', '2461', '1579', 'y', '8623', 'C', 'i']
