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.

Example Input: 5, 5, ['l', '1553', '6191', '3301', 'C', '4133', '8579', 'V', 'b', '7421', '8941', '9721', 'i', 'm', '1383']
Example Output: C
