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, 14, ['d', 'Y', 'G', '5849', '6425', 't', '7727', '7863', '131', '6013', '9683', 'Z', 'n', 'y', 'U', 'g', '8675', '1377', 'L', 'u', '6811']
