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, 27, ['Q', 'p', '1647', 'j', '4151', 'N', '7723', '7355', 'L', 'm', 'p', 'v', 'E', 'A', 'Z', 'K', 'A', '5909', '5489', 'R', '8639', '8945', '679', '4473', 'a', '5089', '1295']
