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: 10, 18, ['f', 'R', 'y', '2995', '6195', '2907', 't', '9035', '8221', '7061', 'd', '6663', '8761', 'n', 'p', 's', '349', 'F', '6003', '3515', 'p', '6995', 'y', 'G']
