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:
10, 14, ['A', 'H', 'L', '8285', '9599', '7453', 'P', 'X', '8827', 'l', '3785', 'f', 'M', '381', 'G', '5633', 'U', 'w', 'X', '8993', '4691']

Ex Output:
