Detailed Instructions: 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.
Q: 6, 13, ['l', 'R', 'y', 'I', 'T', '7181', 'B', 'g', 'G', '8055', '8021', 'O', '6719', '1087', '2839', 'M', '729', '3547', '327', '9099', 'u', 'g']
