In this task, you are given inputs 'i', 'j', and A, where 'i' and 'j' are integers and A is a list. A list is shown by two brackets and comma-separated numbers and characters inside, like ['1', '12', 'l']. You need to concatenate all elements of A from the ith element to the jth element, and then reverse the resulting 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 reverse first and then concatenate.

Example Input: 4, 19, ['o', 'C', 'M', '9251', 'V', '369', '2559', 'w', '5883', 'u', 'b', 'x', '9009', '2981', '2803', 'F', 'j', '2593', 'p', 'D', '8019', 'M', 'W', '7003', 'D', 'B', '9037', 'h']
