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: 10, 11, ['5603', '9103', 'g', 'X', 'l', '2007', 'b', '4629', 'l', 'u', 'X', '1497', 'B', '8853', 'A', '1845', '6859']
