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: 4, 22, ['z', '7693', 'Z', 'h', 'R', 'M', '8357', '7373', '2569', '7189', 'J', 'm', 'Y', 'V', 'x', 'W', 'L', 'J', '375', '7873', 'v', 'o', '6495', 'd', '1459', '1341', 'M', 'e', '3919', 'E']
