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: 9, 18, ['y', 'd', '8047', 'I', 'o', 'b', '2367', '5691', 'v', '4285', '4515', '1', '9687', '6815', 'o', '4693', 'N', '1043', 'L', '6779', '9233', 'P', 'e', '7331', '1219', '3055', '3707']
