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: 1, 7, ['W', 'O', 'O', 'A', 't', 'j', 'r', '5627', 'y', 'l', 'C', '5245', '1373', 'v', '8139', 'E', 'J', 'w', '9331', '6803', 'J', 'o', '6309', 'Z', 'B']
