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.

Example Input: 18, 25, ['c', '5131', '9003', '9289', '825', 'B', '8245', '6175', 'L', '5851', '555', 'h', '8793', 'd', '1833', '2823', 'Q', 'w', '2423', '5363', '2981', '7765', 'q', '8029', 'k']
Example Output: k8029q7765298153632423w
