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, 4, ['7745', '2169', 'j', 'x', '827', 'L', 'F', '6263', '7465', 'U', 'b', 'd', 'e', 'D', 'e', '8471', 'T', '7859', '6433']
