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:
16, 16, ['j', '5995', '1981', 'v', '9505', 'o', '9255', 'A', 'S', '5543', 'U', 'f', '3517', 'T', 't', 'h', '9569', 'i', 'N', '8617']

Ex Output:
