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: 16, 18, ['E', 'l', '2967', 'J', 'V', 'n', '2367', 'n', 't', 'e', 'u', '4255', 'G', '5057', '1105', '9611', 'i', '8805', 'U', '9717', 'F', 'w', 'W', '771', 'x', '6259']
