Definition: 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.
Input: 15, 17, ['9651', 'x', '2783', 'f', 'm', '6627', 'R', '4203', '3133', 'O', '8767', 'I', 'T', '1433', '5429', '7813', 'C', '9753', 'I', 'W', '335', 'f', '1369', '2169', '335', 'd', 'U', 'j']
