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: 11, 12, ['4217', '7725', '1753', '3049', 'd', '5543', 'z', 'o', '8859', '7469', 'M', '3863', '4729', 'K', 'o', 'b']
Example Output: 3683M
