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, ['6855', '6165', 'o', '8699', '3887', '659', '7185', '7243', '7311', 'I', '7531', 'c', '901', 'v', 'C', 'P', 's', '3891', '571', 'g', '7413', 'H']

Ex Output:
I731172437185659
