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:
4, 10, ['x', '6441', 'j', '9963', '4381', '493', 'M', 'V', '9209', '7833', '5569', 'u', '9505', 'p', 'X', '4595', 'b', '5781', '7251']
