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: 12, 23, ['I', 'g', 'K', 'C', '6451', '593', 'p', '1685', 'b', '8659', 'd', 'e', 'X', '6809', 'W', '5949', '505', 'G', '9449', 'B', '3693', 'e', 'M', '2073', 'm', 'A', 'B', 'x', '4475']
