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: 3, 7, ['973', '4113', '517', '6021', '6051', 'H', '3763', 'S', '6425', 'G', '5913', 'U', '1421']
Example Output: 3763H60516021517
