Definition: 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.
Input: 1, 4, ['N', 'm', '643', 'Z', '3109', '1177', '9003', 'F', '7095', 'N', '5255', '8113', '9397', 'H', 'k', 'A', '7515', '2747', '45', 'g', '9047']
