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:
11, 25, ['F', '41', 'Z', 'S', '3451', 't', '6333', 'a', '1351', 'l', '5955', 'm', '1513', '19', 'c', '5079', 'c', '3555', 'r', '153', 'R', 'Q', 'k', '6255', 'I', '1905', 'X', '5595', '6051']
