Definition: 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 find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output 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. Perform the operations in order, i.e., do not concatenate the elements and then reverse the string.
Input: 10, 15, ['J', 'M', 'Q', 'S', 'v', '7373', 'W', 'c', 'I', 'F', 'D', '6605', 'k', '7001', '5017', '4391', '1103']
