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:
2, 5, ['Z', 'X', 'K', '8555', 'B', '3245', '6737', 'c', 'X', '8797', 'x', 'p', 'B', 'M', '7283', '8483']

Ex Output:
B8555KX
