You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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

New input: 9, 12, ['A', 't', 'F', '9571', '8759', 'd', '7519', '8883', '5275', 'B', '6303', 'M', 'h', '3797', 'v', 'p', '757', '9717', 'D', 'o', '9387', '2673', '6343', '7357', '917']
