Teacher: 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 concatenate all elements of A from the ith element to the jth element, and print 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
6, 14, ['9545', '5185', '1667', 'w', 's', '9559', 'T', 'u', 'U', '6843', 'L', 'l', '6365', '7103', 'A', '2381', '5037', 'X', '4487', 'd']
Solution: 9559TuU6843Ll63657103
Reason: Here, concatenating all the elements between the 6th element and 14th element gives '9559TuU6843Ll63657103'.

Now, solve this instance: 18, 30, ['9027', 'z', 'V', '7171', 'J', '463', '2327', 'P', '3479', 'd', 'b', '3689', '1749', '3973', 'g', 'i', 'n', '5951', 'h', '2521', 'b', 'a', 'k', 'J', 'e', '1741', '8547', '4067', 'x', '2941']
