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: 5, 14, ['S', '4231', '6377', '4559', '8213', '2583', 'Z', '3547', '4007', 'm', 'Z', '3671', '6455', '9961', 'm', '8539', '8627', '7379', 'q', '6557', '1469', 'G', '321', 'C', '5671', 'p', 'E', 'h']
