In this task, you are given inputs i, j, and A, where i and j are integers and A is a list. You need to find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output the resultant 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 concatenate the elements and then reverse the string.

Ex Input:
8, 8, ['q', 'u', '2237', '959', '4277', '8467', '7625', 'b', 'i', 'Q', '2685', '2741', 'o', '4991', 'K', '2141', '9273', '8641', 'S', '3179', 'Y', 'W']

Ex Output:
b
