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.

Input: Consider Input: 1, 6, ['i', '8793', 'i', 'E', 'P', 'h', 'v', '4901', 'I', 'E', 'R', '35', '9175', 'G', 'C', '395', '7333', 'q']

Output: hPEi3978i
