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:
6, 10, ['7301', '9619', 'A', 'I', '9195', 'y', 'W', '7281', '4467', 'D', 'J', '819']

Ex Output:
D44677281Wy
