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.

Ex Input:
3, 14, ['J', '3163', 'y', 'o', 's', 'G', '3709', '7903', '3505', 'G', '6615', 'w', '6489', 'L', '1083', 'f', '5657', 'A', 'i', '1955', 'O', '4945', '1243', '5939', 'Q', 'D']
