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.

Ex Input:
3, 16, ['2479', 'F', '5727', '3779', '5749', '4677', 'o', 'P', 'e', '2433', 'z', '3789', 't', 'L', 'I', 'V', 'Z', 'o', 'u', '1209', 'q']
