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, 7, ['j', '6673', 'I', '587', 'S', 'o', '2475', '8581', '571', 'Z', '555', 'k', 'C', 'j', '769', 'd', '6237', 'e', 'T', 'o', 'O', 'b', 'D']

Ex Output:
2475oS587
