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: 3, 10, ['c', 'x', '2543', 'z', 'C', '8873', 'L', '651', 'w', 'I', 'v', '5877', 'f', '4365', 'p', '3465', '3979', '7085', 'y', 'x', '8823', '5833', 'i', 'R']
