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:
1, 5, ['u', '157', '113', '4103', 'n', 'R', '6183', 'e', '439', '9053', 'k', 'z', '8999', '9613']

Ex Output:
