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:
3, 6, ['4031', 'K', 'X', '2743', '453', 'X', '4777', 'T', 'I', '1435', '3873', '3103', '2099', '9651', '2917', '5711', '9881', 'o', 'I', 'p', 'H']

Ex Output:
X4532743X
