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, 16, ['F', 'f', 'p', '2455', 'j', '2579', '4155', 'd', 'A', '1427', 'm', '5187', '2545', '4361', '187', '2025', 's', '9539', '339', '441', '2599', '3407']
