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, 7, ['3145', '4447', 'h', '1723', '2791', '8085', 'H', 'R', '5457', 'F', 'P', 'N', 'u', 's']

Ex Output:
