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: 7, 20, ['M', 'w', '4271', 'S', 'N', '2229', 'I', '5851', 'M', '7427', '9069', '507', 't', '9823', '1015', 'v', '3835', '2015', '3625', 'F', '9195', 'V', '3613', '6431', '3293', '2945', '4373', '2835', 'J']
Example Output: I5851M74279069507t98231015v383520153625F
