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:
15, 17, ['K', 'z', 'u', '6105', 'I', '1915', 'c', '4143', 'S', 'z', 'D', 'K', 'e', 'M', '6925', '7189', '3323', '7977', '7825', 'a', 'd', '9407', '8541', '7869', 'T', '5441', 'W', '3325', 'w']

Ex Output:
