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: 9, 25, ['u', 'b', '4819', 'm', 'm', '1651', 'H', 'O', '481', 'I', 'g', '8861', 'b', '2641', 'D', '5411', '7731', 'I', '257', 'I', '2055', '5441', '7079', 'D', '93', '6783']
