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, 6, ['3619', 't', '7823', 'F', 'c', '7723', '6133', '1819', '955', '8363', 'u', '5461', '529', 'c', '3667', 'a', '7681', 'G', 'R', '9383', 'f', '971', 'W', '9153']

Ex Output:
