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:
1, 10, ['c', '5993', 'n', 'H', '8699', 'v', '5721', '4691', 'P', 'B', 'A', 'r', '2361', '7181', 'm', '5609']

Ex Output:
BP46915721v8699Hn5993c
