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:
4, 11, ['j', '7593', '6631', '5943', '5033', 'f', 'N', '9453', '3353', '1719', 'n', '8353', 'F']

Ex Output:
n171933539453Nf50335943
