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: 4, 22, ['3571', '1503', '5895', '9767', '8373', 'T', 'e', '6479', '3745', 'G', '6421', 'q', '8169', '8869', 'V', 'Y', 'g', '4645', '7061', '3445', 'U', '3331', 'A', 'P', '7689', '5385', 'O', '7341', 'B', '1429']
