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: 13, 20, ['c', '7981', 'Y', '3241', '3245', 'Q', 'E', 'J', '5907', 'm', 'P', 'B', 'o', 'L', '3515', '6679', '4979', '7743', 'A', '7623', 'N', '4887', '4005', 'j', '3413', 'Q', 'V', 'U', '8017', 'G']
