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: 7, 12, ['I', 'Y', 's', 'Y', 'T', '6301', '1327', '6559', 'h', 'J', '7295', '8529', 'b', '4515', '7315', 'n', 'i', '3697', 'u', '6709']
