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:
5, 11, ['i', '1561', 'd', 'a', '2889', 'V', '8371', '521', 'V', '7609', 'M', 'I', '1557']

Ex Output:
