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: 7, 22, ['6261', 'b', 'A', '2725', '5193', '4677', 'U', '8231', 'f', 'S', '3663', 'f', 'f', 'g', '6327', 'g', '2959', 'u', '1385', 'z', '743', '1187']
