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: 3, 17, ['A', '1755', 'I', '9041', '9809', 'y', '7793', 'q', '4603', '8287', '6835', 'U', 'p', '3547', '7373', '2997', '9671', '1079', '7103', '6141', '7807', '6791']
