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.
One example: 1, 3, ['238', 'h', '92', 'U', '2799']
Solution is here: 29h832
Explanation: Here, concatenating all the elements between the 1st element and 3rd element and then reversing the string gives '29h832'.

Now, solve this: 5, 13, ['9129', 'N', 'V', 'G', 'o', 'L', 'm', '6483', '5811', '9687', 'H', '4531', '2913', '7443', 'T', 'C', '323']
