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:
14, 19, ['z', '1543', 'b', 'd', '3025', '4649', '1171', '3355', '307', 'u', 'v', '1651', 'U', '9105', 'I', 'p', 'L', 'N', '9843', 'm']

Ex Output:
9843NLpI9105
