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: 7, 9, ['b', 'z', '4373', 'G', '3677', '2071', '6633', '5615', 'S', '6257', 't', 'a', '1255', '6433', 'y', 'X', '8403', 'H', '8375', '4217', '3221', 'i']
