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:
1, 14, ['9413', 'D', 'd', '7887', '3119', 'b', 'l', 'j', '3801', '1709', 'p', 'I', '1485', '8647', '4095', '9645', '5299', 'g', 'q', '4841', '6937', 'x', '1087', '6063', '2745', '571', '4525', 'c', '4723']

Ex Output:
86471485Ip17093801jlb31197887dD9413
