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: 10, 11, ['5441', 'k', '9573', '4937', '7305', '2303', 'P', 'P', 'N', '2549', 'C', '5865', 'M', '9033', 'k', 'A']
Example Output: C9452
