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.

Q: 7, 14, ['j', '2199', '6995', 't', 'U', 'C', '1589', '7061', '851', 'N', '7923', '7387', '2053', 'L', 'y', '3685', 'X', 'C', '4679', '3691', '2991', 'f']
