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:
10, 16, ['3169', '993', '6245', '3203', '9441', '47', '435', '3305', 'N', '1679', '9655', 'Q', 'j', '4409', 'X', '9031', 'e', 'J', '7379']

Ex Output:
