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