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:
5, 11, ['3133', '3685', 'S', 'c', 'l', '7755', 'I', 'a', 'i', '453', '9037', 'm', '9851', 'd', 'u', '8775', '8379', 'R', '4087', '4541', 'C', '2105', '4117', '3489', '8495', '5441', 'P', '7013', 'I']

Ex Output:
