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: 4, 18, ['g', '3947', 'z', 'n', 'W', '8501', '9869', '4273', '9439', '5445', 'u', '9033', '1749', 'g', 'x', 'w', 's', '6039', '8493', 'l', 'f', '5519', '2145', '3647', '8413', '2865', '8937', '2701']
