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:
7, 25, ['4811', 'm', 'H', '471', '9541', 'D', 'k', '4375', 'z', '3377', '2099', 's', 'f', 'J', 'w', '1075', '5925', 'C', 'l', '6841', 'A', '1341', '5339', 'P', '3153', 'D']
