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: 1, 7, ['6177', '2355', 'z', 'f', 'Y', '5807', '5807', 'k', '6209', 'g', 'Z', 'r', 'E']
Example Output: 58075807Yfz23556177
