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.

Example Input: 1, 7, ['a', 't', 'e', '9279', 'x', 'L', 'i', 'e', 'J', 'g', 'm', '2517', '8937', 'X', '7151', 'u', '4787']
Example Output: ate9279xLi
