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.
One example: 6, 14, ['9545', '5185', '1667', 'w', 's', '9559', 'T', 'u', 'U', '6843', 'L', 'l', '6365', '7103', 'A', '2381', '5037', 'X', '4487', 'd']
Solution is here: 9559TuU6843Ll63657103
Explanation: Here, concatenating all the elements between the 6th element and 14th element gives '9559TuU6843Ll63657103'.

Now, solve this: 13, 18, ['3239', '4359', 'R', 'S', '1587', 'I', '2361', 'o', 'O', '327', '5315', '1555', '4127', 'q', '8959', 'P', 'k', 'h', 'r', 'C', '9073', 'q', '4733', '4143', '5375', 'y', '6157', 'G', 'A']
