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: 5, 25, ['y', 'P', '5747', 'Z', '3129', '6399', '9969', '3889', 'S', 'M', 'N', 'q', '8023', 'A', '2575', 'O', 'c', '7649', 'X', 'H', 'L', 'o', '9841', 'G', 'q', 'b', '8793', '7599']
