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, 3, ['j', 'l', '9447', 'u', '5249', 'F', 'K', 'Y', 'p', 'y', '3643', '8639', 'n', '5883', 'X', 'v', '5079', '9253', 'p', 'x', 'k', '5181', 'E']
