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, 8, ['7425', 'P', 'I', '9705', '1823', '4957', 'c', 'u', '5347', '8853', 'A', 'L', 'W']

Ex Output:
uc495718239705IP7425
